Maybe this was even one of the main reasons why they had to launch the attack because of non retaliation confidence, US has been a major supplier to many countries who have depend on them, this alone cannot make them react even in worst situations.
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. Now Qatar's are giving themselves consolation that this is Israel own move and US is not involve in this operation. Qataris gift of aircraft (worth 400 million usd) to Donald Trump was also not able to stop this attack.
There are reports that Doha attack is carried out by 10 Israels Air crafts flying a 1,800 km route through Jordan, Syria, Iraq, and Saudi Arabia before they released 10 missiles at the Hamas delegation. This also means that missions was not improvised but was a pre-negotiated involving many countries to hit a political target in Doha.
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?
