Comparing the US led effort to look like it is fighting the Islamic State to when president Clinton attacked our long term allies in Serbia is an interesting exercise. For one thing, they seemed to know where every strategic target in Belgrade was, as well as every precious artifact that should be spared for posterity. Clearly under Clinton the US military had some amazing intel and technology. Then you have today, where the US is incapable, by its own admission, of seeing a Toyota Land Cruiser full of jihadis in the desert at night because its lights are out on its way to destroy an entire city of priceless historical artifacts.
Here Charles Krauthammer makes some further statistical comparisons that ought give one pause.
