In November, Iranian naval vessels landed in Durban, South Africa—the closest they have ever gotten to the Atlantic. The Islamic Republic, since 2013, has also engaged in joint naval exercises with Pakistan, India, and China, sending its ships as far as the East China Sea. And more recently it publicized plans to create naval bases in Syria and Yemen. Yoel Guzansky writes:

A base in Syria, if it ever materializes, would stretch Iran’s naval arm to the Mediterranean and strengthen the Iranian military presence near Europe’s shores. It would also help Tehran’s allies in Lebanon, Gaza, and Syria—Hizballah, Hamas, and the regime of President Bashar al-Assad, respectively. A naval base in Syria would enable Iran to transport regular supplies and provide other assistance to Hizballah without being dependent on overland convoys or aerial transport through Iraq or Turkey. The base would also make Iran less dependent on Sudan, [which has been distancing itself from the Islamic Republic] . . .

If left unchecked, Iran could potentially develop the capacity to threaten crucial shipping lanes in the Caspian Sea and the Indian Ocean. As a result, Iran’s recent announcements of its plans to expand its regional presence to the Red Sea and the Mediterranean could spur cooperation between Israel, which is also seeking to curb Iranian influence, and the Arab world. For its part, the United States under President Barack Obama has shied away from confrontation with Iran in almost all instances. The U.S. Navy has chosen not to counter the increasing provocations in the Persian Gulf by Iran’s Islamic Revolutionary Guard Corps Navy. As of September 2016, there had been 31 “unsafe encounters” with Iranian vessels in the Persian Gulf, up from 23 in 2015, according to the U.S. Navy. The lack of action is costing Washington its credibility as a counterforce to Tehran.

The incoming Trump administration should do more to counter the threat posed by Iran, particularly in the naval arena, where the United States enjoys clear superiority. It should draw firm “redlines” around Iranian naval actions—to ensure that Iran’s provocations won’t be left unanswered and to demonstrate Washington’s resolve.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
