President Trump’s insistence that the United States do less toward securing Europe means that allies, scrambling to arm themselves, have less to give to Ukraine.

The European Union will allocate an additional €900 million from extraordinary revenues generated by frozen Russian assets for the purchase of weapons and ammunition for Ukraine, increasing the EU’s recent total support for Ukraine’s defence industry to €3.

The EU could greatly increase its military support to Ukraine if Russia isn't convinced by Donald Trump's efforts to make peace, an official said.

US tariffs on defense components risk disrupting arms supplies to Ukraine, raising costs and straining NATO supply chains. Bosnia, a key ammunition producer backed by US investment, could be caught in the middle.

They said that if President Vladimir V. Putin did not agree to the cease-fire, more sanctions would be imposed.

Weapons maker Michal Strnad likes to say he works in the business of defense. As Europe re-arms on a massive scale, it’s proving a lucrative place to be.

In Sweden, as across Europe, defense spending is soaring — but too slowly to meet Russia’s threat. STOCKHOLM — Europe’s race to rearm is accelerating at warp speed — and not nearly fast enough.
