It's not something to undertake lightly.
I read that Sweden during ww2 shot at both ally and axis aircraft that flew over their airspace. Distressed planes were allowed to land, but the crews were incarcerated...and put in luxury hotels. A secret ally operation later in the war, was bringing the ally airmen back home.
Meanwhile, at the end of the war, the Swedes turned about 3,000 germans over to the Russians. The Germans were so angry about being turned over to the russians, that they began riots, killed themselves, began hunger strikes and self mutilation campaigns.
Google searching newspaper archive articles is pretty cool for the history buff.
Not unless you are Mexico and fly your choppers into the USA at will.

Israel tends to regularly overfly Lebanese airspace. The Lebanese military also regularly responds with AA fire or SAMs.
This really isn’t all that much in the way of news.
(Most likely, Israel wanted closer reconnaissance of Hizbollah sites. Something better than what satellites could give.)
