In 2016 the US lost track of $1B worth of weapons in Iraq alone

Well it's hard to say if they lost track or never tracked the transfers. Here's the story. There is zero accountability. And the Donald wants to give more weapons to the Kurds and sell $110B in arms to the Saudis to continue their war in Yemen. People never learn.

A billion here. A billion there. Eventually the federal government may start being concerned with real amounts of money.
