Russia appeared to brush aside President Donald Trump’s threat to impose tariffs against Moscow and its trading partners if its war with Ukraine does not end in 50 days, but there are signs of growing concern among some factions of the nation’s elite that an opportunity may have been missed.

Russia continued its nightly bombardment of Ukrainian cities overnight into Tuesday, after President Donald Trump said the U.S. would send military equipment to Kyiv.

Trump’s U-Turn seems partly the result of European leaders, Rutte especially, who worked hard to develop common ground with the U.S. President. It also seems to be the result of growing irritation with Putin. Trump said Monday that Putin talks “so beautifully” when it comes to a ceasefire but “then he’ll bomb people at night. We don’t like that.”
