Qatar has one of most advanced Air force yet everyone is sure that Qatar won't give any response to Israel aggression. It's Qatar today, whose next?
the attack was not on or aimed for "qater" it was aimed for hamas..
heck even you admit to know that certain facilities have their own sovereign territory in other hosting countries, which separates them from the hosting country in way, diplomacy and such
as you say one such other example
US Central Command has its headquarters at the Al Udeid Air Base Qatar and that's why it's impossible for anyone to come near to this area without US permission. In fact Gulf countries have given there lands to US for military bases with mindset that such moves will make them safe.
