If the same Mexican terrorists had killed eight of our soldiers, and had killed them at the bidding of Vicente Fox, and this killing was only the latest in a long line of killings and terrorist activity, the US military would own Mexico City.
Ah, there's the rub. Are you saying that the government of Lebanon ordered the kidnapping of these soldiers? I haven't even heard the Israeli government claim that. This is more like a raid by a Poncho Villa-style terrorist organization. When that happened to the US, the army went after the bandits - we didn't go to war against the entire Mexican nation.
