You've been warned, so don't respond as if I'm being serious...
The real reason why we are in Liby is..............to prevent DADT from being removed in the military!!! We previously discussed in the DADT thread that the DoD agreed to lift DADT as long as we're not in the middle of a war. So, to keep from lifting it, we will continue to engage in new wars... Brilliant!
Seriously though, as I stated before, there will probably not be a time in the near future when we are not fighting a war. That change will happen whenever the DoD feels like making that change, which technically may not ever happen.
