President Donald Trump may have expected a Russian shudder of fear to greet his threat of “very severe tariffs” on the country if it didn’t agree a ceasefire in Ukraine.

Trump has criticized the Russian president in unprecedented terms in recent days and signaled he’ll send vital weapons to Ukraine.

The plan, which Trump and NATO Secretary General Mark Rutte hatched in recent days, according to two sources familiar with the discussions, has been received positively by Ukraine and its allies.

U.S. President Donald Trump said he was disappointed but not done with Russian President Vladimir Putin, according to a BBC interview published on Tuesday, hours after Trump announced new weapons for Ukraine and threatened Russia with sanctions.

Donald Trump is growing impatient with Russian President Vladimir Putin, publicly lamenting earlier this week the fact that Russia hasn't agreed to a peace deal with Ukraine.

European powers and Ukrainian officials say they do not believe Putin is serious about peace and have implored Trump to abandon his efforts to repair relations with the Kremlin.
