I’m not too worried as Humvees and other equipment require high maintenance and specialized replacement parts.
Now if they can procure the parts and mechanics through some provided source, that’s another matter.
True; the Ayatollah ended up with modern US jets that couldn’t fly because they had no parts or people to maintain them. Just the same, it is disgraceful; those that say we just go to war for business are vindicated when we’re even manufacturing materiel for the enemy...
