As the war shifts to the strategically important Donbas region of Donetsk, the US and its allies need to continue to do everything in their power to arm Ukraine with all the weapons they need. Doing so is the only way to push Putin's forces back as was done in Kyiv.
As stated by Putin, the whole purpose of the war was never to invade Kyiv, but to liberate the ethnically Russian people of Donetsk and Luhansk, who have been subjected to systematic killing by Ukrainian forces for not recognizing the 2014 coup in Kyiv.
More weapons packages will make little difference in the outcome of the war. The US has been meddling in Ukraine since the end of the Cold War, and what we're witnessing is a geopolitical ponzi scheme to benefit those aligned with the military-industrial complex. War is a lucrative racket.
