A diplomatic truism is that some conflicts are insoluble. They are, however, manageable. Although the consequences of doing nothing or mismanagement can spell disaster. The Arab-Israeli conflict falls neatly into the above category.

President Joe Biden obviously came to this conclusion before stepping on the plane for his tour of the Middle East this week. A succession of American administrations – except Trump’s – has paid homage to the two-state solution. Biden reiterated the pre-Trump position, but not as forcefully as his predecessors. Part of the reason is that there was little point as his Israeli counterpart, Yasir Lapid, is merely a caretaker prime minister while the Jewish state struggles through another political crisis. As for the Palestinians, they are hopelessly divided between Hamas in Gaza who are a designated terrorist organisation and the PLO’s Mahmoud Abbas who, at 86, makes Biden look like the proverbial spring chicken. The result is that the two-state solution has been moved from the backburner to refrigerator.

Instead the US administration is focusing on maintaining relations with Israel and trying to draw other allies – mainly Saudi Arabia but also the United Arab Emirates and Qatar – into closer relations with Israel. To help with the first point, Biden has toughened his stand on Iran and the threat of nuclear weapons. One thing that all Israeli parties agree on is that Iran represents an existential threat. Biden has agreed that he will do whatever is necessary to prevent Tehran from acquiring nuclear weapons. The second issue is more, problematic, especially as regards Saudi Arabia. There is no love lost between Saudi Crown Prince Mohammed bin Salman (MBS) and Biden and the wider Democratic Party. Clearly a problem that needs managing.

Ukrainian military commanders are cock-a-hoop. The military equipment and training provided by the West are starting to work, especially the shoot and scoot American High Mobility Rocket Systems (HIMARS). The GPS-guided precision artillery have to date knocked out 19 forward-based Russian ammunition dumps.

The Ukrainians are now talking about a major counter-offensive involving hundreds of thousands of ground troops to retake territories lost in the Donbas Region. There are, however, problems. HIMARS rockets are accurate and effective, but they are also expensive and have to be used sparingly. So far the US has supplied eight launchers. Another four are on the way. The other problem is that their range is limited to 50 miles. As the Ukrainians advance, the Russians could simply stage a tactical retreat and still control a significant slice of Eastern Ukraine. Washington could supply Ukraine with precision weaponry with a range of 500 miles. These would be a war-winner but would mean that Ukraine could strike targets inside Russia which means escalation with disastrous consequences.

Meanwhile there appears to be the possibility of some movement on the movement of grain out of Ukraine. Between them, Russia and Ukraine account for 21-28 percent of the world’s grain supplies and 40 percent of this vital food for the inherently unstable North Africa and Middle East. A big chunk of that grain is – more than 20 million tonnes – trapped in Ukrainian siloes, unable to reach hungry world markets because of a Russian naval blockade. This week saw talks in Istanbul involving Ukrainian, UN, Russian and Turkish negotiators. They ended with Turkish Defense Minister Hulusi Akar promising a signed deal next week. Moscow and Kyiv have said nothing.

There are several sticking points. For a start the Ukrainians have mined the approaches to their ports to prevent a Russian amphibious landing and the Russians have imposed a naval blockade to stop the import of weapons. Going into this week’s talks Moscow demanded the right to inspect incoming ships for weapons. The Ukrainians said no. The Ukrainians, for their part insisted on grain carriers being escorted by convoys of friendly ships. That is a possibility and Turkey may play a role here.

A further complication, however, is that the exports would include Russian grain which Ukrainians assert has been stolen from land occupied by the Russians since their 24 February invasion.  Not surprisingly, UN Secretary-General Antonio Guterres has said: “There is still a way to go.”
