In the heaviest onslaught since 2014, southern Israel was attacked from Gaza this week by Islamic Jihad and Hamas launching dozens of rocket and mortar attacks, as well as bursts of machine-gun fire. An Israeli kindergarten was hit, although no one was hurt. After Israel pummeled terrorist targets, Egypt brokered a truce.

What was striking was that the Israel-averse European Union, United Nations, France, Italy, Germany and Ireland criticized the Gaza attackers and expressed support for Israel.

France declared that its commitment to Israel’s security was “unwavering.” Germany said the targeting of Israeli civilians was “malicious,” and that it was “Israel’s right to preserve its security, defend its borders and respond proportionately to attacks.”

Yet two weeks earlier, when Israel defended itself against the attempt by Hamas to storm the Gaza border and murder Israeli civilians, those same European nations and the United Nations grossly misrepresented what happened as the killing of unarmed civilians in “peaceful protests,” despite the vast majority of those killed by Israel being Hamas terrorists.

So what’s changed? Well, first of all, the situation on the ground.

When Hamas began its weekly riots at the Gaza border fence, some took this as the sign of an inevitable escalation to all-out war. Yet on May 14—the day of the heaviest onslaught that provoked the E.U. criticism—Hamas abruptly called off its invasion. Whatever the reason, the decision was taken to cool it.

Then suddenly, Islamic Jihad—aided and abetted by Hamas—launched its missile onslaught. It was clear this did not enjoy wide support. Russia didn’t want it. Egypt didn’t want it. The Gulf states will tolerate nothing that gets in the way of their tacit alliance with the United States and Israel against Iran. Even Hamas reportedly got cold feet over the scale of the attack.

So who wanted it? Step forward the Islamic Republic of Iran, backers of Hamas and patrons of Islamic Jihad. And why did Iran want it? Because the regime is distinctly rattled.

America’s withdrawal from the nuclear deal has thrown it into disarray. The United States is threatening to impose condign sanctions. The Iranian rial is in freefall. The recent speech by Secretary of State Mike Pompeo extended U.S. policy way beyond curtailing Iran’s nuclear activities.

Iran, he said, must stop supporting Hezbollah, Hamas and Islamic Jihad, support disarming Shi’ite militias in Iraq and withdraw from Syria. The United States would work to counteract its cyber activities, track down its operatives and proxies and “crush” them.

Israel is now destroying more and more Iranian assets in Syria with U.S. backing.

Moreover, a wedge is being driven between Russia and Iran. Russia needs stability in the region to safeguard its interests. The last thing it wants is for Israel to be drawn further into Syria. So Russia is trying to keep Iranian forces away from Israel’s northern border and has said the Islamic Republic should pull its forces out of Syria once a political settlement is reached.

Galvanized by the new U.S.-led dynamic, the Iranian people are continuing to revolt. There’s now a Twitter hashtag in Farsi calling for regime change, as well as another that reads: “Thank you Pompeo.” If this escalates, the Iranian people can bring down the regime.

In the space of a few months, therefore, it has gone from being an unstoppable regional force to scrabbling to survive. So in desperation, it is playing two of its remaining cards.

The first was using its proxies in Gaza to unleash the missile barrage against southern Israel. The second is its urgent wooing of the European Union to persuade it to defy the American call to impose global sanctions.

At this moment, the European Union chooses to back Israel against the Gaza missile barrage—the same European Union that all but ignored the missile barrages that led to the 2014 Gaza war in which, of course, it denounced Israel for finally defending itself.

When it came to the Gaza border riots, however, the European Union was not united in its condemnation of Israel. The Czech Republic Foreign Minister Martin Stropnický said rushing the security fence should be regarded as a form of terrorism.

Earlier, Hungary, Romania and the Czech Republic had blocked an E.U. statement condemning the U.S. embassy move while other countries, including Slovakia, Greece and Poland, reportedly also expressed reservations. On Monday, European foreign ministers discussed Gaza at their monthly meeting but failed to issue a statement, a sign they didn’t agree.

But the real reason for the E.U.’s surprising change of tone is surely that the presence in the White House of President Donald Trump has changed everything.

America backed Israel strongly over the Gaza riots. While eight E.U. members lined up at the United Nations to call on Israel to refrain from using “excessive force” against “peaceful protests,” the U.S. ambassador Nikki Haley said the violence came from those who rejected the existence of the State of Israel. “Such a motivation—the destruction of a United Nations member state—is so illegitimate as to not be worth our time in the Security Council, other than the time it takes to denounce it.”

The European Union is beginning to grasp that the implicit criticism of those who fail to join the United States in supporting Israel carries consequences. President Trump has made it clear that he expects European and other countries to support him in imposing sanctions against Iran. If they don’t, they will have to choose: trade with Iran or trade with America. They can’t do both.

Meanwhile, Italy is politically imploding and threatening the whole E.U. project. The financier George Soros has said the European Union is now facing an existential crisis.

Is the E.U. going to choose this moment to get up America’s nose still further? Hardly. So it was presumably anxious to demonstrate to Trump that, despite its earlier sanitizing of Hamas as “unarmed protesters,” it was really against Hamas after all.

If so, such declarations won’t cut it. For the world has reached a tipping point, and Iran is key. To avoid a truly terrible conflagration, the Iranian regime has to be brought down.

Israel, the United States, the Gulf states and the Iranian people are behind such a strategy. Astoundingly, Britain and the European Union stand with the regime against them. They must now decide if they will join the attempt to defeat the forces of evil—or else suffer the consequences.
