If there are no big surprises in the region – and there don’t appear to be any on the horizon — there are likely to be several stormy days over the weekend, and not because of the weather.

In fact, an improvement in the weather is likely to make the protests in the West Bank, East Jerusalem and Gaza — which began Thursday with a Fatah-organized general strike in Palestinian cities, and are likely to intensify on Friday — even more tempestuous.

Thursday’s strike at schools, stores and businesses meant Palestinians, notably younger Palestinians, were free to take part in Fatah protests in the city centers. And from there it is a short path to the checkpoints with Israel.

The Palestinian Authority and Fatah are organizing the rallies in the city centers, but a key question is whether the Palestinian security services will stop demonstrators from reaching the potential flashpoints. In light of the Palestinian-Arab-Muslim consensus against US President Trump’s decision to recognize Jerusalem, PA security may receive orders not to step in to block protesters on their way to the checkpoints, except, perhaps, to prevent the use of firearms.

This week marks 30 years since an IDF truck collided with a civilian car in Jabalia refugee camp in Gaza, killing four Palestinians, which led to the outbreak of the First Intifada, also known as the stone-throwing intifada. Friday may see a repeat of some of those First Intifada-style confrontations but on a larger scale. This time Hamas is already calling for an intifada.

A very large number of people are expected to participate in protests Friday, with calls in the mosques to protect Jerusalem and the Temple Mount (or, as Trump called it, Haram al-Sharif) and nonstop broadcasting on Palestinian TV of clips showing past violence around Jerusalem.

A small reminder – Ariel Sharon ascended the Temple Mount on Thursday, September 28, 2000, and nothing much happened right then. The explosion of violence took place immediately after prayers on Friday, September 29, when riots broke out on the Temple Mount, leading to police going up to the site, the deaths of 13 worshipers and the start of what become the Second Intifada.

The next test will be what happens after Friday. Will the momentum continue? How much energy does the Palestinian public have for yet another conflict?

Obviously much depends on Israeli security forces’ ability to contain the protests without too much bloodshed.

And much will depend, too, on how Palestinian Authority President Mahmoud Abbas chooses to act.

In deep sea diving, nitrogen narcosis can cause symptoms of drunkenness. The deeper one dives, the greater the feeling of drunkenness. You lose your sense of orientation and your judgment, and sometimes get vertigo.

When Abbas began his diplomatic campaign against Trump’s decision, it is unlikely he imagined how successful he would be. He didn’t change Trump’s mind, but almost the entire Western and Muslim world — basically the whole world outside of Washington — has expressed clear support for the Palestinian leader. This success, in turn, gave rise to quite a few demands by the various Palestinian leaders and camps who wish to take over the leadership of Fatah from Abbas come the day — calls to announce the cancellation of the Oslo Accords, to renounce the political peace process, to return to a First Intifada kind of “struggle.” This last demand is being promoted by supporters of Marwan Barghouti, who is currently serving five life sentences in an Israeli jail for his role in murderous terror attacks during the Second Intifada in the early 2000s.

For his part, Ismail Haniyeh, head of the Hamas political bureau, is calling on the Palestinians to mount an intifada to liberate Jerusalem. It is fascinating to see how, despite the ostensible reconciliation process between Hamas and Fatah, Haniyeh and his movement are openly trying to take control of the campaign that began on Abbas’s desk.

Abbas probably wants to mobilize the Palestinian public to take a belligerent line against the US and Israel, while making sure he doesn’t completely destroy everything. The problem is that the deeper this crisis gets, the more Abbas may fall prey to some of those deep sea diving symptoms — to take a more confrontational stand and try on the “freedom fighter” persona adopted by his predecessor Yassar Arafat. One can only hope that Abbas knows when to cut short the dive and hurry back to the surface.

In a discussion with a Palestinian official on Thursday morning, I got the clear impression that Fatah and the PA had not delved too deeply into the details of Trump’s speech. The US president’s decision to endorse a potential two-state solution, the decision to move the embassy in the long term not the short, and the clarification that the boundaries of Israeli sovereignty in Jerusalem must be negotiated with no change to the status quo at the holy sites plainly did not interest him or his colleagues. When I asked him, in reference to the Palestinians’ unbridled opposition to Trump’s moves, “Where will this all lead?” he could not restrain himself. Citing Arafat’s notorious call to war, this official declared: “Millions of martyrs marching to Jerusalem.”
