When Peggy “Dolphins Saved Elian Gonzalez” Noonan says that she thinks that an American war is stupid:

The biggest takeaway, the biggest foreign-policy fact, of the past decade is this: America has to be very careful where it goes in the world, because the minute it’s there — the minute there are boots on the ground, the minute we leave a footprint — there will spring up, immediately, 15 reasons America cannot leave. The next day there will be 30 reasons, and the day after that 45. They are often serious and legitimate reasons.

So we wind up in long, drawn-out struggles when we didn’t mean to, when it wasn’t the plan, or the hope, or the expectation.

We have to keep this phenomenon in mind as we chart our path in the future. It’s easy to start a war but hard to end one. It’s as simple as that. It’s easy to get in but hard to get out. Even today, in Baghdad, you hear that America can’t leave Iraq because the government isn’t sturdy enough, the army and police aren’t strong enough to withstand the winds that will follow America’s full departure, that all that has been achieved — a fragile, incomplete, relative peace — will be lost. America cannot leave because Iraq will be vulnerable to civil war, not between Sunnis and Shiites, they tell you now, but between Arabs and Kurds, in the north, near the oil fields.

She is, of course, writing about the war du jour, Libya, and she is correct.  It’s a bad idea.

What’s more, when this operation is well within the capabilities of other countries, either the UK or France could likely do this on their own, and certainly can do this together, so say nothing of the contributions of Italy and Canada (!?!?!?!), there is no need for any contribution to the kinetic portion of the war by the US, though satellite and signals intelligence could certainly make a difference.

A reader of Americablog nailed what is driving the American involvement in this:

The main reason the US seems to want to be involved seems to be to avoid being left out. If the UK and France could take out Libya on their own, people might start asking if the US really needs to have a military an order of magnitude larger than the UK and French forces combined.

Our bloated giant Pentagon cannot allow our allies to engage in a kinetic war (i.e. shooting) without a major involvement, because if they do, it casts doubt on the raison d’être for us to spend more on our defense than the rest of the world combined.

So, not only does the fact that we are a military behemoth make us stay in places that we have never gone, it makes us go places we should never go, because to stay home when others go would put its continued support at risk.
