No. But there are plenty who think it's necessary for reasons that are amoral at best, and are willing to excuse it as collateral damage toward a "greater" cause. The question is, is it really necessary to dominate the world militarily? Can we defend ourselves and live peacefully? Is it necessary to project our power to the furthest corners of the globe with overt and ubiquitous threat of violence? It seems we may have found a functional limit on how much power military dominance affords a nation.
To be clear - I'm not opposed to a strong military, I want the strongest deterrent we can afford. But I want a military that protects the homeland first and foremost, and avoids indulging mercantilism for the elite.
It means something to be a super power. It means being able to project power over the globe. There are many advantages to that, not just for the U.S. either. Many places would long ago have destabilized into civil war if we weren't around.
Collateral damage happens in war. If terrorists hide among children then children are going to get killed. Why aren't you blaming the population that allows terrorists in their midsts, leading to the loss of children's lives?
You are simply the flip side of Obama's blame America first policies.
