The US has given its entire stockpiles of land war weapons to Ukraine. And is giving its entire stockpile of air war weapons to Israel.
The US hasn't given Ukraine or Israel anything but ageing platforms that were ultimately up for retiring in any significant numbers, and most of the aid money "given" to Ukraine has been spend in the US modernising production facilities and working on replacements for the gear that was sent.
What they have given away was never going to see any use in a conflict outside of WWIII. While it would be nice to think they couldn't do anything about Venezuela, they still have thousands of tanks, artillery pieces, fighter aircraft and bombers.
How?
