In Iraq and Afghanistan, Obama has increased the use of drones and decreased the use of "boots on the ground". What has been the result? More US casualties than under Bush, and increased instability of the governments in those nations and increased casualties to civilians in those nations inflicted by the enemy.
Has there been a political benefit despite these bad military results? NO. Islamism is on the rise from Mali to Libya to Egypt to Syria to Iraq and Afghanistan. Pakistan is less stable, too. And Iran is closer than ever to a nuke. Meanwhile, China and Russia act-out ever more adventurously in the Pacific (and via North Korea and Iran - their clients). And our European allies are economically weaker than ever.
ALL IN ALL, OBAMA'S FOREIGN POLICY HAS BEEN AN UNMITIGATED DISASTER. For the West that is. Russia, China, Iran, and the islamists have done rather nicely.
It matters not if this was by design or by incompetence or just the inevitable result of appeasement and Pollyanna-ish policies. It's been a disaster. That the overwhelming majority in the West don't see this is sad.
The majority will eventually wake up from their propaganda-induced delusions, but it may very well be too late and because of an overwhelming catastrophe - that's too big to handle.
