JERUSALEM Deceased Hamas terrorist leader Yahya Sinwar envisioned that his invasion of Israel on Oct. 7, 2023 would prompt his allies Hezbollah and all the Iran-backed proxies to launch a full-scale war against Americas key Middle East ally, Israel.The long-stated goal of the troika of terrorist regimes Hamas, Iran and Hezbollah was the end of the Jewish state.What Sinwar dreamed about on October 7, however, has turned into a series of devastating unintended consequences for Hamas in the Gaza Strip, Hezbollah inLebanon and the regime's "Axis of Resistance."TRUMP ADDRESSES NATION ON 'SPECTACULAR MILITARY SUCCESS' OF US STRIKES ON IRANIAN NUCLEAR FACILITIESPresident Donald Trumps decision to attack Irans core nuclear facilities on Saturday was perhaps the most telling example of Sinwars plan being turned upside down.A leading Israeli security expert from the Israel Alma Research and Education Center, Sarit Zehavi, told Fox News Digital, "In general, if you talk about the October 7 effect, this is truly a huge change in the Middle East."The running list of setbacks for the enemies of America and Israel starts with the degradation of Hamas in 2024.Israel executed a James Bond-style operation on July 31, 2024, resulting in the elimination of Ismail Haniyeh in Iran, the Palestinian terrorist who oversaw the Hamas Political Bureau. Iranian Supreme Leader Ali Khamenei, who is currently hiding in a bunker, pledged retaliation.In October 2024, Israel killed Hamas Gaza-based leader Sinwar. Just last month, Israeli Prime Minister Benjamin Netanyahu announced his countrys forces had eliminated Sinwars brother, Mohammed, a key terrorist responsible for the construction of the massive terror tunnel system on Israels south border.TRUMP PROMISES TO RESPOND WITH 'FULL STRENGTH AND MIGHT' OF US MILITARY IF IRAN ATTACKS AMERICAThe Israel Defense Forces' (IDF's) targeted killing of Hezbollahs leader, Hassan Nasrallah, in September 2024 was part and parcel of the Jewish state's successful campaign to decapitate the leadership of the terrorist group in Beirut.Just days before Nasrallahs demise, Israels foreign intelligence agency, Mossad, activated a hack attack that caused explosions of handheld pagers carried by thousands of members of Hezbollah.In December, Fox News Digital exclusively reported on Hezbollahs secret plan to invade Israel.Israels decimation of a significant part of Hezbollah seems to have generated deterrence. Hezbollah has not entered the current full-blown war between Israel and Irans regime. Tehran expected Hezbollahs intervention in a war with the Jewish state.ISRAEL SAYS IT KILLED IRAN'S 'SENIOR-MOST MILITARY OFFICIAL'Zehavi said while Sinwar perhaps made a tactical decision to invade, she cautioned about giving too much credit to Sinwar.She noted Mohammed Said Izadil, who Israel reportedly eliminated on Saturday and who oversaw the Palestinian affairs branch in the Quds Force, the branch of IransIslamic Revolutionary Guards Corps, was "deeply involved" in the planning of the invasion on October 7. Zehavi noted that documents found by the IDF in Gaza revealed that Izadil knew in advance about Hamas intent to invade Israel on October 7.CLICK HERE TO GET THE FOX NEWS APPZehavi, who is an IDF lieutenant colonel (Res.), said, "It is too soon to tell where those changes will lead us" in the Middle East. The first effect of October 7, she said about the enemies of Israel and the U.S. in the Middle East, is, "Israel can no longer tolerate monsters who threaten its very existence. We are eliminating those monsters one after the other, with the support of the United States, which is also very important." She warned, however, that the open question is, will the terrorist regimes and organizations recover?"
