A plan for NATO to expand its Iraq mission by taking personnel from the anti-ISIS coalition could satisfy US President Donald Trump's call for more alliance action in the Middle East, a US official said Tuesday (February 11th).

NATO defence ministers will meet in Brussels this week to discuss a proposal to move some forces from the US-led coalition fighting the "Islamic State of Iraq and Syria" (ISIS) to NATO's training mission in Iraq.

Kay Bailey Hutchison, Trump's ambassador to NATO, welcomed the move, saying it would leave coalition forces free for more combat operations against ISIS remnants in Iraq.

"It is part of burden-sharing -- our European allies coming in with us and doing more in counterterrorism," she told reporters.

"The NATO operation is already ongoing in Iraq and I think it will definitely be an answer to what President Trump has requested."

Trump called on NATO to do more in the Middle East in January, days after a US drone strike killed top Iranian commander Qassem Soleimani in Baghdad.

The January 3rd strike sparked a vote by the Iraqi parliament to oust all foreign troops -- including 5,200 US soldiers.

The anti-ISIS coalition halted its campaign for three weeks in response, and NATO stopped training activities while insisting it remained committed to helping Iraq.

In recent weeks, NATO officials from Secretary General Jens Stoltenberg down have been engaged in frantic diplomacy with Washington and Baghdad to seek a way out of the crisis.

They want to protect gains made against ISIS, which at its peak controlled large areas of Iraqi territory.

A plan to transfer some coalition forces -- who number some 11,000 across Iraq, Syria and Kuwait -- to NATO's structures has already won support in Baghdad, according to diplomatic sources.

Spanish transfer

There had been hopes that officials could draft a concrete proposal for ministers to formally approve in Brussels this week, but political turmoil in Iraq has slowed the process.

One NATO official said that, for now, discussions were focusing on "functions not figures" -- what the transferred troops would do rather than how many of them would move.

A diplomatic source said Spanish forces training Iraqis under the coalition could be moved to the NATO mission, effectively doing the same job but under a different banner.

But training of Iraqi special forces would still be carried out by US troops as part of the coalition, the source added.

Stoltenberg said no decisions had been made but said the NATO mission would continue to focus on training Iraqi forces and would not take on combat operations, insisting "prevention is better than intervention".
