Why did we need them in the first place - especially that many? Nothing happened!
The rulers might say that nothing happened because there were troops there; not provable.
It reminds me of the mythical town in Arkansas that was afraid that some time they might be overrun by elephants. They hired a thousand hunters to watch every entrance and all the streets 24 hours a day 7 days a week. After a year they had a meeting to see if the expenditure for all those hunters was worth it. They determined that since no elephants had been seen in that yearly period the program must be a huge success. :^)
Typical bureaucratic nonsense.
Since Trump authorized the troops, there must be a reason for them that has not yet materialized.
