One of the effects of the Wikileaks document dump has been to undermine the case for the war on terror by showing how many of the supposed reasons were fabrications, as well as the opinions of the allies of the US with regards to the war on terror.
Of course, apologists for war point out the necessity of each involvement. But examining the root of each argument finds that the arguments themselves are unsupported. Each intervention is necessary because of the prior intervention, but what was the basis for the prior intervention? The War on Terror is a result of the interventions during the Cold War, the Cold War was a result of interventions during World War Two, and World War Two was a result of interventions during World War One, but what was the basis for intervening in World War One?
It is an elaborate interdependent structure, each piece connecting to every other piece, every facet supported by some other facet, and the whole structure supported by absolutely nothing.
That is important. The whole structure is supported by nothing.
That is what Wikileaks has shown us. There is no support for this whole structure. The US has a military presence in so many countries around the world because the US has a military presence in so many countries around the world. It is not in actual defense of anything, unless you count bases in one foreign country defending bases in another foreign country.
Of course, noticing this will get a person labeled "Isolationist" by those who refuse to tell the difference between "isolationist" and "noninterventionist." Yes, all isolationists are by default noninterventionists, but not all noninterventionists are isolationists, with some preferring to have peaceful relations with all and entangling alliances with none.
So the reason there are bases all around the world waging war in distant lands? It is to keep the peace, because if the US were not waging war on everyone there might be war, even war against the US. Instead the US is waging "peace" in Afghanistan, waging "peace" in Iraq, and threatening to wage "peace" against Iran as a way to prevent the US from having to wage war.
It’s nothing more than a circular argument suspended in midair. Wikileaks has committed the crime of pointing that out.
