Don't you think it is time for the USA to deploy "Q Ships" to lure in Somali Pirates?

An interesting question, but think about the economics of the situation. Right now, who's paying and what are the losses? I think if you work it out, you'll find that the costs are being passed back down to the people who buy things and/or taxpayers. Accordingly, neither the shippers nor the insurers have any great incentive to spend any money that will cut into their profits. As for the government, what would it cost to do this, and would it be worth it? That's hard for most of us to answer, since we don't really have access to the cost figures associated with present naval deployment versus refitting/deployment of Q-ships (presumably additional to rather than a replacement for). Also, there's the inherent conservatism of military operational thought, which isn't enthusiastic about embarking on relatively different and unusual operations. I suspect that some mixture of blockading and convoying is far more likely to be undertaken when the Navy feels that the present laissez-faire system is becoming too dangerous.
