I agree with you. Biden should have provided Ukraine with all the necessary resources to defeat Putin decisively. However, this approach risked escalating tensions and potentially triggering World War III with significant US casualties.
While I firmly believe the war must end, I worry about Trump handling Ukraine as he did Afghanistan; essentially surrendering it to the Taliban. This wouldn't solve anything but postpone future conflicts, leaving the region more unstable and vulnerable.
Any resolution to this conflict must address both Ukraine's and Russia's concerns, not Russia's alone.
