1- Cyprus is equiped to down them and if they ever do they will be fully supported by the international community (EU at least) so Israel is not that stupid
2- They fly over Syria

@JustLeb It is not their business how the lebanese defense strategy is organized. In short 7ejje ma bte2le 3ejje and this is coming from someone who in general prefers a conditional peace treaty w nekhlas ba2a.
I ‘m not calling to Israel approval , I ‘am calling to apply your constitution ( only the army has weapons) , the taef agreement, international resolutions 1559 and specially 1701 . Stop

giving exuces to Israel to interfere in Lebanon, let the state be in control and let us be a normal country not a militia under Iran orders fighting Iran wars all over the Middle East with the result that a country is isolated and under a financial blocus .
They left Egypt who is sovereign, all these countries control their airspace, Syria is a pariah nation today unfortunately. This is not our case , we could be independent only if we apply international law , are we members of the UN , Our Constitution stipulates that
Lebanon is also a founding and active member of the United Nations Organization and abides by its covenants and by the Universal Declaration of Human Rights. The Government shall embody these principles in all fields and areas without exception.
Go apply the Constitution , taef , and international resolutions; this is the best way how a small country will be secure
