Funny Trumps advisor stated one of the options was BOOSTING support for Ukraine to the point Russia was forced to the table. Funny how that option which would be much more aligned with American's past actions, commitments, policy stance, and allies wasn't chosen but this 'predictable' one was, especially by a President that likes to claim he takes action via strength (but chooses this weakening of his sides negotiating position).
Yes. And in fact the Trump Administration may boost military aid to Ukraine in the future still.
This was mentioned in the above thread: "A direct confrontation between NATO and Russia is another, much less likely alternative. The idea that Russia's economy will collapse is highly unlikely."
The approach to try to force Russia to concede to Ukrainian demands and back down would require boosting Ukraine military aid, but would either fail and result in a forever war, succeed by collapsing Russia's economy (highly unlikely to succeed), or result in a direct NATO-Russia confrontation.
In terms of America's past actions, the history is loong, but if you are referring to the Biden Administration - it had a strategy up until the Ukraine military faltered in its failed counter-offensive.
Anyway, you expect policy changes between administrations.
