NATO chief Jens Stoltenberg has proposed a $100 billion military aid package for Ukraine over five years that would give the Western alliance a more direct role in supporting Kyiv, five diplomats told Reuters on Tuesday.

Under the plan, NATO would take over some coordination work from a special U.S.-led coalition known as the Ramstein Group, a move partly intended to protect against any reduction in U.S. support if Donald Trump returns to the White House, diplomats say. .

The proposal is expected to be discussed at a two-day meeting of NATO foreign ministers on Wednesday and Thursday to finalize a package of measures for the NATO summit in Washington in July.

Until now, NATO as an organization has limited itself to non-lethal assistance to Ukraine, fearing that a more direct role could provoke an escalation of tensions with Russia. Most of its participants supply arms to Ukraine on a bilateral basis.

But diplomats said there is a growing sense within NATO that the time has come to provide military aid to Ukraine on a more sustainable, long-term basis, and that the Western alliance is best suited to take on a larger role.

Some also said that Russian President Vladimir Putin’s threats that he would view various measures taken by NATO allies as provocative have not led to retaliatory action against them.

As part of the plan, the organization will create a NATO mission in Ukraine, although it is not yet clear whether the mission will operate inside the country, diplomats say. Some countries were afraid to even call the operation a mission.

Stoltenberg, NATO’s secretary general, said the plan is partly to “protect against the winds of political change” in any NATO member, but Trump is uppermost in the minds of many, a senior NATO diplomat said.

NATO declined to comment in detail on Stoltenberg’s proposals, but a NATO official said foreign ministers would “discuss how best to organize NATO’s support for Ukraine to make it stronger, more predictable and more resilient.”

“No final decisions will be taken at ministerial meetings in April and discussions will continue as we approach the Washington summit in July,” the official said, declining to be named.

Diplomats warned that negotiations on the proposal were at an early stage and it was not clear whether all 100 billion euros would be accepted or how it would be raised. All NATO decisions require consensus among the alliance’s 32 members.

“It will protect to some extent if Trump is elected. But it is impossible to create something resistant to Trump,” another diplomat said.

“A fund of 100 billion looks very optimistic, knowing how difficult it was to reach an agreement on a smaller amount at the EU level,” the diplomat added.
