When the Iranians used Russian targeting assistance to hit our headquarters facilities, aircraft, and logistics bases in the Gulf, they blew up our resupply. And the supply and refueling ships havent been sent in because the military doesnt know if they can protect them. A lot of the ordnance that wasnt fired was destroyed in storage. The US war fighting capability has been seriously diminished by the loss of ordnance, food, and fuel. Thats why Trump is begging our NATO allies who he just spent the last year insulting and denigrating.
And, add to that the part of the military budget spent replacing Border Patrol with US troops on the border so they can add to the racist deportation task force and sending Nat Guard to cities to suppress public dissent and thats why the military is running out of money.
Also, they just started canceling military schools and training so if Trump puts boots on the ground they will be out of practice with their mission essential tasks as will the Guard troops deployed to border patrol duty and civil intimidation duty.
