Jordan is currently massing forces on the Iraq border. This relates to something that has long bothered me.
Ultra-radical Islamic fundamentalism threatens all other forms of government: democracies, republics, even monarchies. Jordan,Saudi Arabia, the United Arab Emigrates, Oman, Quwait, Bahrain, Qatar, etc. are all very far from free societies, but the leaders and their lifestyles are all threatened by extreme groups like ISIS in Iraq.
The thing is that it is their immediate problem in their backyard, not ours. We can no longer be the policemen of the world. Why are we even discussing re-invading?
All the countries I mentioned have plenty of money, with large and modern armies and air forces. These forces are virtually next door, not half-a-world away. They could and should handle the problem, not us.
All that is needed to make a happy life is within yourself, in your way of thinking. -Marcus Aurelius
