I'm suspicious of this. Have you seen the what kit the Qatari military have? They are easily in the top 3 in the region, with the Saudi's. The west has sold them a massive amount of modern hardware, even at Fairford they had Apache Guardian on display, this is an attack helicopter that the British Army have only just got their hands on.
It is very strange that Israel were able to make such an incursion without any response. The Israeli jets were not stealth and they only used JDAMs which don't have much range.
