> Support Ukraine enough so it can take all its territory (maybe minus Crimea). This may not be possible with weapons alone. This might require a NATO no-fly zone over Ukraine, which effectively makes us a combatant. I actually would support this path, but the downsides are all too obvious.

It _is_ possible with the combo of weapons and economic sanctions. Ukraine (had) more economic support, so it is both a war of blood and endurance, endurance which Ukraine could have by being a porcupine with next-gen weapons and non-stop bleeding for Russia until things start hitting the oligarch's pocketbooks too far and the people of Russia begin to demand regime change.

Russia is a glorified gas station. You can hurt it dramatically with economic sanctions because its whole GDP is concentrated into one sector.

Imo if Trump really cared about America's long term security, he would be trying to fund research into cheaper / easier to produce next-gen weapons for Ukraine to test for us, instead of complaining how much our HIMARS and tanks currently cost, firing top military brass, cozying up to a dictator, and trying to exploit a ravaged democratic ally.
