IDF and Mossad are indeed state of the art in border security and intelligence. Giving them the benefit of the doubt as a whole, there must have been at least some crazed, apocalyptic faction within one or both of those entities that purposefully allowed for this LARGE scale planning outside their borders and execution within their borders to proceed uninterrupted.
Meanwhile the neocons over here, with their histrionic outrage are implicitly rejoicing over the tragedy, since this is one big step closer to a decades old wet dream of invading / destabilizing Iran. It is good to recall Wesley Clark's statements back in the 2000s about having been privy to plans going back to the 90s to have multiple other nations on the neocon hit list, below Iraq, for invasion/destabilization: Afghanistan, Iran, Syria, Libya, etc.
And their domestic allies and supporters? Mainly all the politically "conservative" Western evangelicals under the religious psy op of Dispensational / Second Coming madness, which is in perfect geopolitical alignment with British + Israeli Zionism, including the Israeli zealot faction who are on board with military violence as the means of ushering in their Messiah. How convenient.
They will get THEIR MESSIAH: John 5:43 New International Version I have come in my Father’s name, and you do not accept me; but if someone else comes in his own name, you will accept him.
Dan.8:23 “In the latter part of their reign, when rebels have become completely wicked, a fierce-looking king, a master of intrigue, will arise. 24 He will become very strong, but not by his own power. He will cause astounding devastation and will succeed in whatever he does. He will destroy those who are mighty, the holy people. 25 He will cause deceit to prosper, and he will consider himself superior. When they feel secure, he will destroy many and take his stand against the Prince of princes. Yet he will be destroyed, but not by human power.
2Thess. 2:. 8 And then the lawless one will be revealed, whom the Lord Jesus will overthrow with the breath of his mouth and destroy by the splendor of his coming. 9 The coming of the lawless one will be in accordance with how Satan works. He will use all sorts of displays of power through signs and wonders that serve the lie, 10 and all the ways that wickedness deceives those who are perishing. They perish because they refused to love the truth and so be saved. 11 For this reason God sends them a powerful delusion so that they will believe the lie 12 and so that all will be condemned who have not believed the truth but have delighted in wickedness.
