Some conservative members of Donald Trump's "Make America Great Again" movement have reacted angrily to the president's plans to sell weapons to Nato, arguing it is a betrayal of his promise to end US involvement in foreign wars.

Trump said the United States would put secondary tariffs on countries that do business with Russia if a peace deal is not reached in 50 days.

Though endlessly critical of his predecessor, President Trump has adopted a Ukraine strategy similar to that of former President Joe Biden: Arm the Ukrainians to the teeth and threaten Russian President Vladimir Putin with even more sanctions if he does not agree to a peace deal.
