I will forego giving you a list of the current programs of record and asking where to take the carve out. But in practical terms, we are spending defense budget funds on Ukraine. When we throw them the keys to all those howitzers and give them all that ammo, that's coming out of our defense stocks. Those items will need to be replaced.
I haven't seen the draft budget, but we are expecting a "resource constrained environment" for the foreseeable fiscal years to rebuild readiness. In other words, DoD will eat some of the cost of replacing what we give to Ukraine.
Also keep in mind the figures you hear about how much more we spend on defense are often bogus. If you relook China's math or consider comparable salaries and production costs you see we're not just pouring funds into the military industrial complex.
