I love when brutal dictators get to use chemical weapons.

58. Depends on what you mean by "active"

Israel's filed missiles into Syria, fire has been traded between the IDF and rebel fighters in southwestern Syria, and I've read that there are Israeli patrols that go as far as ten miles past the armistice line with Syria, so Israel is already involved...

But if you mean actually trying to get involved more deeply than that? Not unless some Syrian faction or other drags Israel into it with a big attack or two. Syria's not a fight that Israel wants. In fact I rather imagine it would respond to even major attacks simply with a few more missile strikes, so it can "hit back" but without committing fully to combat operations - particularly if it comes from one of the rebel factions. I could be wrong, but frankly I'd rather not find out either way.
