Having a physical troop presence in any foreign country seems sort of outdated with the drones and everything.
It used to make sense because you had to deploy troops to occupy an area and keep it under control.
Now the wars are fought on the internet, with currency devaluation and with drone strikes.
Saddam couldn't win with tanks and troops against technology in the 90's. Just imagine how such a war would play out 30 years later.
The actual combat in any recent war with NATO involvement was over within a week or less.
After that it's an insurgency or terrorism and guerrilla warfare that most nations are ill equipped to deal with.
The war on Libya lasted until the UK and France ran out of cruise missiles.
The time that you could win a war by physically marching your troops into someone elses capitol is over.
And no one wants to deal with the shit in the conquered country anyway as they have their own shit to deal with already.
