Putin, unfazed by Trump, will fight on and could take more of Ukraine

Russian President Vladimir Putin intends to keep fighting in Ukraine until the West engages on his terms for peace, unfazed by Donald Trump's threats of tougher sanctions, and his territorial demands may widen as Russian forces advance, three sources close to the Kremlin said.

Putin, who ordered Russian troops into Ukraine in February 2022 after eight years of fighting in country's east between Russian-backed separatists and Ukrainian troops, believes Russia's economy and its military are strong enough to weather any additional Western measures, the sources said.

Trump on Monday expressed frustration with Putin's refusal to agree a ceasefire and announced a wave of weapons supplies to Ukraine, including Patriot surface-to-air missile systems. He also threatened further sanctions on Russia unless a peace deal was reached within 50 days.

The three Russian sources, familiar with top-level Kremlin thinking, said Putin will not stop the war under pressure from the West and believes Russia - which has survived the toughest sanctions imposed by the West- can endure further economic hardship, including threatened U.S. tariffs targeting buyers of Russian oil.

"Putin thinks no one has seriously engaged with him on the details of peace in Ukraine - including the Americans - so he will continue until he gets what he wants," one of the sources told Reuters on condition of anonymity due to the sensitivity of the situation.

Despite several telephone calls between Trump and Putin, and visits to Russia by U.S. special envoy Steve Witkoff, the Russian leader believes there have not been detailed discussions of the basis for a peace plan, the source said.

Putin's conditions for peace include a legally binding pledge that NATO will not expand eastwards, Ukrainian neutrality and limits on its armed forces, protection for Russian speakers who live there, and acceptance of Russia's territorial gains, the sources said._Agencies.
