In the 52 years since Israel seized the Golan Heights from Syria, there have been multiple efforts to negotiate their return in exchange for Damascus ending its continuous war against the Jewish state. Shmuel Rosner argues that, with his announcement on Thursday acknowledging the legitimacy of Jerusalem’s claim to the Golan, Donald Trump has finally decoupled territorial concessions from peacemaking:

[With] the takeover of much of Syria by Iran and its proxies, . . . Israel had no choice but to give up on the idea of withdrawing from the Golan Heights. But this reality involves a complete overhaul of the way the international community thinks not just about the Golan Heights but also about all of the lands Israel occupied in 1967. . . .

Withdrawal worked for Israel once, in 1979, when it signed a peace agreement with Egypt and left the Sinai Peninsula, which had also been occupied in 1967. But that also set a problematic precedent. President Anwar Sadat of Egypt insisted that Israel hand back the entire peninsula to the last inch. Israel decided that the reward was worth the price, as a major Arab country agreed to break with other Arab states and accept Israel’s legitimacy.

But there was a hidden, unanticipated cost: Israel’s adversaries, in future negotiations, would demand the same kind of compensation. The 1967 line—what Israel controlled before the war—became the starting point for all Arab countries, including Syria. It became a sacred formula, worshiped by the international community.

What President Trump is doing extends far beyond the ability of Israel to control the Golan Heights, to settle it, and to invest in it. The American president is setting the clock back to before the peace deal with Egypt, to a time when Israel could argue that the reward for peace is peace—not land. Syria, of course, is unlikely to accept this. At least not in the short term. But maybe someday, a Syrian leader will come along who doesn’t entertain the thought that Israel might agree to return to the pre-1967 line and who will accept a different formula for achieving peace.

Early Friday morning, Israel attacked military installations near the Iranian cities of Isfahan and nearby Natanz, the latter being one of the hubs of the country’s nuclear program. Jerusalem is not taking credit for the attack, and none of the details are too certain, but it seems that the attack involved multiple drones, likely launched from within Iran, as well as one or more missiles fired from Syrian or Iraqi airspace. Strikes on Syrian radar systems shortly beforehand probably helped make the attack possible, and there were reportedly strikes on Iraq as well.

Iran itself is downplaying the attack, but the S-300 air-defense batteries in Isfahan appear to have been destroyed or damaged. This is a sophisticated Russian-made system positioned to protect the Natanz nuclear installation. In other words, Israel has demonstrated that Iran’s best technology can’t protect the country’s skies from the IDF. As Yossi Kuperwasser puts it, the attack, combined with the response to the assault on April 13,

clarified to the Iranians that whereas we [Israelis] are not as vulnerable as they thought, they are more vulnerable than they thought. They have difficulty hitting us, but we have no difficulty hitting them.

Nobody knows exactly how the operation was carried out. . . . It is good that a question mark hovers over . . . what exactly Israel did. Let’s keep them wondering. It is good for deniability and good for keeping the enemy uncertain.

The fact that we chose targets that were in the vicinity of a major nuclear facility but were linked to the Iranian missile and air forces was a good message. It communicated that we can reach other targets as well but, as we don’t want escalation, we chose targets nearby that were involved in the attack against Israel. I think it sends the message that if we want to, we can send a stronger message. Israel is not seeking escalation at the moment.
