The United States has such a large GDP because 1/3 of it is the private healthcare industry. Another massive chunk is the government throwing tax dollars at a shell company of a shell company of a shell company that moves a government contract for construction around to each other 4 times, all subsequently increasing GDP.
The US install literal military bases complete with airfields and air conditioning in the middle of the desert after invading and occupying it lol. They can’t do it after being invited to the region?
