Washington (CNN)The Trump administration, which has disdained truth , is now facing a tough burden of proof and history as it barrels toward a confrontation with Iran.

US, after two years systematically building economic, diplomatic and, finally, military pressure on Tehran — that was bound to trigger a response from its bitter foe.

President Donald Trump’s pyrotechnic approach to the presidency has solidified his base but alienated half the country, a factor that would complicate his efforts to sell Americans on another war.

And Trump’s incessant fight against fact and denials of obvious truth may also mean he has a credibility issue even if he comes before the nation to talk about what he sees as a credible threat.

There is also suspicion among American allies and domestic critics of Trump about the motives of key players on the White House team, uncertainty about the President’s sometimes erratic instincts and wider disdain for his bulldozing foreign policy.

Bolton is on record before he joined the Trump administration calling for regime change in Iran and US bombing, and his new power is providing a troubling reminder for American allies of the run-up to war with Iraq.

Bolton was a hawkish member of the Bush administration that used now-discredited intelligence about weapons of mass destruction and hyped the threat from Saddam Hussein that led America and its allies into a quagmire in the Middle East.

Trump denied on Wednesday that there was any disagreement inside his administration about Iran policy and sought to show in a tweet that he was in control.

“Different opinions are expressed and I make a decisive and final decision – it is a very simple process. All sides, views, and policies are covered. I’m sure that Iran will want to talk soon,” Trump tweeted.

He suggested that the President was losing patience with Bolton and Secretary of State Mike Pompeo over their aggressive approach to Iran, which he fears runs counter to his reluctance to get embroiled in major conflicts like the Iraq War.

Switzerland acts as a diplomatic proxy for the US with Iran in the absence of diplomatic relations, and the meeting may be a sign that Trump wants to push for dialogue with Tehran — however unlikely such a scenario appears to be.

Pompeo has been frenetically traveling to and from Europe, stiffening US rhetoric on Iran, though he insists Washington is not trying to provoke the Islamic Republic into war.

In another foreboding sign, the administration pulled most of staff from embassy in Iraq warning of threats in a country where pro-Iranian militia operate.

Unnamed US officials have said Iran or the United Arab Emirates including two Saudi tankers and a Norwegian flagged vessel. So far they have presented no evidence of Iranian involvement.

State Department officials said Tuesday the threat to US interests in Iraq was similar to what was seen at a previous time of tension with in 2011, including the possibility of barrel bombs, explosives targeting diplomats’ homes and rockets targeting diplomatic compounds involving militia groups sponsored by Iran’s Islamic Revolutionary Guard Corps.

In a region as consumed by conflict, conspiracy theories and power struggles as the Middle East the fog of war is always thick. It could well be that Iran is deliberately testing the US in response to Washington’s own escalation and that the administration is simply passing on and not exaggerating threats.

There is no argument among the US and its allies that Iran is often a nefarious influence. But the question is how to deal with it.

In an extraordinary statement issued hours later, a spokesman for US Central Command said Major General Chris Ghika’s comments “run counter to the identified credible threats available to intelligence from U.S. and allies regarding Iranian backed forces in the region.”

The rebuke came a day after British Foreign Secretary Jeremy Hunt said he was worried about a US-Iran conflict “happening by accident” on the back of suddenly rising tensions.

European foreign ministers did not offer Pompeo a group meeting during his sudden visit to Brussels this week, perhaps fearing a photo-op would be seen as an endorsement of the US approach.

Sen. Tom Cotton, R-Arkansas, a proponent of a robust US foreign policy, told CNN’s Christiane Amanpour that warnings of a rising Iran threat to US forces were sincere.

“That British general and I may have a different kind of interpretation of that threat or how severe that threat is,” he said. “But I can only say that on the Senate Intelligence Committee, we’ve seen in recent days heightened reporting about potential threats to US personnel and our allies in the Middle East, and we take that very seriously.”

The administration will attempt to convince less supportive lawmakers after offering a briefing for “Gang of Eight” congressional leaders on Thursday.

Logical consequence of events

In many ways, the Trump administration is now reaping what it has sown with a domestic approach that often challenges established fact and a foreign policy that has often gone out of its way to insult and demean allies while elevating US adversaries.

European Union states all but begged Trump not to pull out of the Iran nuclear deal signed by the Obama administration — noting that US intelligence agencies assessed that Tehran was in compliance with the accord.

The rising tensions between Iran and the US might be seen as a logical consequence of events that flowed from Trump’s decision — that appeared more influenced by political than diplomatic motivations. The White House argued correctly that the international accord did not halt what Washington sees as destabilizing regional activity, including missile launches and support for extremist groups.

But its supporters say it put a decade-long lid on Iran’s nuclear program — the only way it can pose an existential threat to its enemies — in return for a lifting of sanctions.

If the deal collapses completely and Iran decides to enrich uranium to weapons grade, Trump could face a decision on risky military action that could cause shock waves around the world and provoke full-scale war.

Alarm bells are ringing among Trump critics because the cranking up of tensions appears to be largely orchestrated by Bolton.

Bolton is on record before he joined the Trump administration calling for regime change and his new power is providing a troubling reminder for American allies of the run-up to war with Iraq.

Bolton was a hawkish member of the Bush administration that used now discredited intelligence about weapons of mass destruction and hyped the threat from Saddam Hussein that led America and its allies into a quagmire in the Middle East.

Trump denied on Wednesday that there was any disagreement inside his administration about Iran policy and sought to show in a tweet that he was in control.

“Different opinions are expressed and I make a decisive and final decision – it is a very simple process. All sides, views, and policies are covered. I’m sure that Iran will want to talk soon.”

The Iraq war’s still potent influence on politics in Europe cannot be underestimated and might tie the hands of any allied US leader if asked to join a US coalition against Iran.

Trump’s unpopularity in Europe and his disregard for its leaders and priorities — including the nuclear deal and the Paris climate accord — are also an impediment to his subordinates as he seeks to sell his Iran policy.

The Trump administration is yet to provide any public proof of its allegations about a rising Iran threat. And the drip, drip, drip of accusations against Iran by anonymous officials in the media is a reminder of the campaign for war with Iraq in the 2000s.
