I am not a betting man. If I was, I would wager a $200 donation to the Salvation Army or Samaritans Purse that there is zero military activity towards Syria in the next 8 months :)
Like I said before it depends what you difine as military activity, we are training Kurds to go on missions, collect data, and blow stuff up, I wouldn't be suprised if we send some of them to deal with some al-Qaeda camps in Syria. Beyond that you are probably right.
