You cant blame him. The Ukraine war supporters are able to send billions of dollars worth of weapons and military equipment. The defense contractors make a fortune from it and the politicians who support it get huge kickbacks. There is not a major US military presence on the ground so they dont even have to worry about US soldiers coming home in body bags so it all reward with almost no risk.
Of course it is the American worker who ends up footing the bill so that defense contractors and politicians can get rich but they will never tell you any of that.
There are 40,000 US troops in Poland right now. Right at the border with Ukraine. They could end up fighting Russians if the Plan B which is direct conflict with Russia to save Ukraine happens. Ukraine is losing very badly, now with huge casualties in the thousands. It may not be long before Russians are facing off with US troops and a lot of them will come back in body bags if it happens.
