While Trump has repeatedly said that he could end the war in Ukraine very quickly, he has never actually said he would end arms shipments to Ukraine. That is speculation from the Western Press outlets such as the NY Times in the U.S., CBC in Canada, and The Times in the U.K. all of whom despise Trump and can't be trusted to report on him fairly or accurately. American aid to Ukraine is 8 X the next closest supporter of Ukraine, the U.K. Since this is a European war, why aren't the European countries stepping up to provide their 'fair share' of support to Ukraine? Further, it is hypocritical in the extreme to condemn Russian aggression while simultaneously buying their natural gas which pays for Putin to invade Ukraine! My take? The longer Ukraine bleeds Russia dry the better since Putin is unlikely to take on a much strengthened NATO (thanks to Trump) after years of expending lives and equipment in Ukraine. Further, the longer the war in Ukraine goes on the greater chance Putin will suffer an "accident" at the hands of a Wagner group member or someone similar. Putin won't have to worry about losing face if he's dead.
America also needs to be prepared for war in the Pacific with an increasingly belligerent China. We have fewer allies in that part pf the world, Japan, Korea, and Taiwan would all step up but the bulk of the fighting would (again) have to be done by Americans. A war in the Pacific would quickly become personal for my family as I have a nephew in the USMC who currently posted in Japan. If American resources are diverted and drained away in Europe, wouldn't that encourage China to start WWIII by invading Taiwan? There is much more at stake here than the Crimea and Donbas regions of Ukraine which is what any American president must consider.
