What do you mean?
I would suggest that you look up “foreign military sales” to see how it works and who really pays.

Hint
YOUR tax dollar at work someplace else...
In other words, we give Israel "store credit" and they use it to buy American jets, helicopters, tanks, missiles, and other weapons.
Apparently this year they want to use some of the credits to buy diesel and jet fuel for their military.
