a synchronized launch of 2000 state-of-the-art HIMARS rockets
Just on a practical level alone, Ukraine got sent at most around 40 of those systems and each one can only fire a 6 rocket salvo.
The US would need to send almost 5x-10x more HIMARS systems than they did. They wiki says over 540 built so at best you're talking sending like 60-80% of all HIMARS systems to Ukraine.
Considering how many of these are not even in the US...
But sure there are other things the west could have done I agree.
