The day of reckoning is here.

For over 30 years, the United States government and the institutions that drive public opinion have made like Susan Rice when it comes to the ideological threat that Islamic supremacists pose to freedom, fabricating reasons to remain in denial. Thus inured, the American people have elected, and now reelected, a president notoriously fond of America-bashing Islamists. The attraction would not be hard to understand if we were not so ideology-averse — GOP strategists having made Obama’s radicalism a subject nearly as off-limits as Islamic supremacism, helpfully leaving the Left to fill the canvas with their portrait of Mitt Romney: “Where Gordon Gekko Meets Michael Vick.”

The president is a movement leftist who sees in our society a condemnable legacy of racism, imperialism, and economic exploitation that cries out for “fundamental change.” That is not meaningfully different from the Islamist perspective of America: The Brotherhood’s self-proclaimed mandate to “eliminate and destroy Western civilization from within” by “sabotage” is, in effect, a cognate summons to “fundamental change,” even allowing that Islamists are driven to statism by sharia rather than Marxism. The Brotherhood’s American mouthpiece, the Council on American-Islamic Relations, brags that the president nabbed 85 percent of the Muslim vote on November 6 — larger even than Obama’s lopsided share of the Hispanic vote, which has GOP strategists hyperventilating. You wouldn’t want to take CAIR claims at face value, but their ardor for Obama, like the Brotherhood’s, is palpable. And as we’ve seen for four years, it is not an unrequited love.

So along comes Hamas. Just days before the presidential election, the terrorist organization — begotten by the Brotherhood and serving as its Palestinian branch — spearheaded an Islamist offensive, firing in just a few days over 120 rockets into the Jewish state from its home base in Gaza. You may not have heard about it until a few days after the election. Like Iran’s act of war in shooting at a U.S. drone in international waters, it signaled a further dangerous unraveling of the Middle East that undercut the media narrative of Obama as foreign-policy chess master, so it was tucked under the rug. But it could not be ignored forever, for it is not just another spike in the ever-thrumming Gaza border skirmish. It is the renewal of an unending war — an existential one for Israel, which is expected to fight “proportionately,” with both hands tied behind its back, yet blithely accept, as the international community has, the barbaric Islamist claim that nothing short of Israel’s destruction will be satisfactory.

By its own declaration, Hamas will be at war with Israel until the latter’s demise. Toward that end, the jihad has now been taken to population centers such as Tel Aviv. As of this writing, the Israeli death toll stands at three, kept low only by the crudeness of the jihadist weapons and tactics.

By the calculation of terrorism analyst Ryan Mauro, the onslaught begun last week brought the yearly total of missile attacks on Israel to about 700. That is, while the Obama administration has been facilitating the Muslim Brotherhood’s rise in Egypt, Tunisia, Libya, and soon Syria — with Obama drawing ever closer to Turkey’s Islamist prime minister, Recep Tayyip Erdogan, even as Erdogan champions and funds Hamas — Gaza’s jihadists have been emboldened to step up their terror campaign.
