I can understand main will here is to see this war end as soon as possible.
The question is what will be the fastest way to do it ? Will more arms for arming Ukraine end the war sooner or not.
There are two things that have changed in recent weeks that now need to be considered.
First Ukraine has proven it can take a lot of land back , and might actually win this war.
The other thing is Putin mobilization , that demonstrate he has no intention of ending this war any time soon , by some sort of a compromise.
As much as this mobilization exposed Russia weaknesses and was subject for jokes , still US can't just ignore this move. It will need to match the Russians mobilization by strengthening and resupplying Ukraine . At least to the level where they can fend of any Russians new attacks

It depends. This war will NOT end with Ukraine took back all their territories, be it pre-2022 or pre-2014. This war can only end when Russia ambition in Ukraine is quashed, once and for all, otherwise even if Ukraine expelled the Russian completely on the ground, as long as Putin is still in charge or whoever take over still have ambition in Ukraine, that will follow a low-high-low intensity conflict between the 2 countries.
The only way to end this war is when we get Ukraine NATO membership or security guarantee to that level, before we didn't do that because again, we don't want to be antagonising Russia, but now Russia had invaded, all bets are off, I think all cards should be on the table, and what this counter offensive show Ukraine is worthy of NATO membership, I think they probably fought better than most country in NATO. So until NATO membership or some sort of legally binding security pact is secured for Ukraine, this war will not end.
For this war to end, it also depends on how or what Ukraine want, do they want to take back all of Ukraine? Or do they just want to get back to Pre-2022 line. That was said by Zelenskyy many times, it depends on what the Ukrainian people want, they would have to vote for any cease fire agreement. And Ukraine have demonstrated that they have the requirement to retake their land, Crimea included.
In fact, what my friend said to me this morning is very funny, but true, what if NATO offer Ukraine membership for NATO now that Russia escalated to annex those part of Ukraine? I think we should call Russian bluff, and see how it goes on the other hand, and let them taste their own medicine, I mean if Russia is allowed to do that, why not the west cannot offer Ukraine NATO Membership? That would solve 2 things. 1.) It will stop Russian from further attacking Ukraine, any missile landed in Lviv, Kyiv, Odessa or Kharkiv would be considered an act of war on NATO, article 5 applies, and we rollback Pre-2022 for Ukraine. If Russia decided not to attack, then there will be peace for what left of Ukraine. The downside is, Ukraine would have to accept the loss of their territories for the NATO membership, not sure how Ukrainian People will take that.
But other than that, I don't see a way this war is going to end soon, or quickly, even after Ukrainian repel all Russian advance.
