It's already happened and settled sensibly:
“Russian pilots occasionally cross into Israeli airspace, but due to excellent defense coordination that began with Netanyahu’s meeting with Putin in which limits were set, the Israel Defense Forces and the Russian military agreed on security arrangements,” said General (res.) Amos Gilad, head of the Israeli Defense Ministry’s political-security division, as reported to Israeli media outlets.
The security protocol established between Israel and Russia should prevent incident like the one of Nov. 24 and the subsequent diplomatic crisis.
He added, “In the understandings with the Russians, we retain freedom of action in our attempts to prevent weapons getting through from Iran to Hezbollah.”
Violations regularly occur elsewhere.
