There are a number of reasons why this has happened. Some more nebulous than others. There are a number of extra powers granted to the Executive during a time of war that Congress didn't want activated. There are a number of requirements that kick in when war is "legally" declared that Congress didn't want activated as well.

I'm not saying drone strikes aren't shady, but they aren't strictly illegal. This is a case where Congress needs to get it together and start overseeing if they want it to stop happening. Otherwise, we're just left depending on diplomacy or the UN trying to put a stop to it, which likely won't happen either.
