It's pretty well known that our military bribed warlords in Iraq and Afghanistan to do chores for our guys, like blow up people we didn't like, or to pay off farmers for not growing opium poppies. And it's true we fund various militias to fight against our current enemy. An army runs on food and weaponry, and lots of it.

Regarding cockroaches, they are ubiquitous in East Coast cities, including in the mansions of the wealthy. Even new construction is almost instantly infested. Washington DC is a big Eastern city and it is cockroach infested. The White House probably requires  fumigation from time to time. It really is no big deal. Trump Tower almost certainly has cockroaches, as well as Mar-a-Lago. Florida  is the promised land for roaches. Trump International Hotel, a very old post office building, no doubt also has cockroaches.

Roaches and rats are found almost everywhere you find people.
