To deter China and stop a resurgent Russia.
Brandon didn’t like them when he was threatening Poroshenko to withhold money unless he fired the prosecutor who was after Burisma. He was shamed into pretending to help Ukraine. Spending hundreds of billions of dollars on Ukraine is just another way of spending hundreds of billions of dollars. Arms industry likes it. Brandon and his cronies get kickbacks. But he makes sure not to give Ukraine anything that might cause victory for Ukraine, just an endless war. No F-16s. No tanks until the Russians have had time to plant vast anti-tank mine fields. Only two batteries of Patriots. But, yes, hundreds of billions.
It does deter China. It does stop Russia. But a swift and decisive victory for Ukraine would have put paid to Russia and deterred China twice as well. Only then there’s no money for the Military-Industrial complex, nor kickbacks for corrupt politicians in the US.
Brandon doesn’t LIKE Ukraine. He uses Ukrainians as human shields for his efforts to undermine the US for fun and profit. Would you do that to someone you LIKE?
Nobody saves you for free.
