Dubai-- Washington wants to build a global "coalition" against the Islamic Republic,  the State Department said on Thursday, after pulling out from the Iraninfo-icon nuclear accord to the anger of USinfo-icon allies.

The plan is to be detailed on Monday by the top United Statesinfo-icon diplomat, Secretary of State Mike Pompeo, in his first major foreign policyinfo-icon address since taking office in April.

"The US will be working hard to put together a coalition," State Department spokeswoman Heather Nauert told reporters.

The aim is to "bring together a lot of countries from around the worldinfo-icon with the specific goal of looking at the Iranian government through a more realistic lens" which would include "all of its destabilizing activities that aren't just a threat to the region but are a threat to the broader world," she said.

She evoked a comparison with the US-led international coalition against the Islamic Stateinfo-icon (Daesh) group in Syriainfo-icon and Iraqinfo-icon.

Begun in 2014, that coalition now counts as members 75 countries or institutions and intervened militarily against the terrorists, although only a minority of coalition members have conducted most of that military action.

Nauert did not say whether the proposed coalition against Iran would have a military component.

She said the State Department received on Monday about 200 foreign diplomats to explain to them US President Donald Trumpinfo-icon's decision to withdraw from the nuclear accord, and the next steps.

Withdrawing from the deal last week, Trump called for a new agreement with deeper restrictions on Iran's nuclear program as well as curbs on its ballistic missiles and its backing for resistance groups across the Middle Eastinfo-icon.

Along with Iran the other signatories of the 2015 deal -- Franceinfo-icon, Britaininfo-icon, Germanyinfo-icon, Chinainfo-icon and Russiainfo-icon -- strongly criticized the US withdrawal.

On Thursday the European Unioninfo-icon said it will begin moves to block the effect of reimposed US sanctions on Iran as efforts to preserve the nuclear deal deepened a transatlantic rift.

Asked about the potential willingness of European nations to join the proposed new coalition, Nauert said many US allies "fully understand" and are "not turning a blind eye" to Iran's actions.
