The Israel Air Force has been getting a little rusty from inactivity. They can use the target practice.
If and when the Hizbullah makes a massive attack against Israel, the IAF will have a private shooting gallery. By the way, did you know that the IAF has all of the same guided munitions that the USA used so successfully in Afghanistan and Iraq?
This has all happened before, it will all happen again. In the 1973 war, the PLO launched their conventional ground force, a regimental-strenght 5,000 man Palestine Liberation Army into the fray from Syria. It suffered 99% casualties.
