U.S. President Joe Biden and Ukraine's Volodymyr Zelenskyy are men of different generations, countries and styles — and with very different missions.

Zelenskyy is fighting to save his nation. Biden to restore a shattered world order — without igniting a world war.

A year ago, Naftali Bennett was struggling for his political survival as Israel headed toward its fourth consecutive election. Today, the Israeli prime minister is at the forefront of global efforts to end the war in Ukraine.

Just as Bennett took advantage of unique circumstances to become the most unlikely of prime ministers, he has managed to leverage Israel's good relations with both Ukraine and Russia and his personal rapport with their leaders to turn himself into an unexpected mediator.

The U.S. says Russia has asked China to provide military assistance for its war in Ukraine, and that China has responded affirmatively. Both Moscow and Beijing have denied the allegation, with a Chinese spokesperson dismissing it as "disinformation."

Still, the claims have generated conjecture over how far Beijing would be willing to go in backing its "most important strategic partner," as China's foreign minister recently described Russia.

With Russia's war on Ukraine now in its third week, Russian President Vladimir Putin on Friday approved bringing in volunteer fighters from the Middle East, particularly Syria.

Syria clearly has a rich pool of fighters to draw from. Russia's military is deeply entrenched in the Mideast country, where its intervention - starting in 2015 - helped Syrian President Bashar Assad gain the upper hand in the ongoing, 11-year civil war.

Russia's invasion of Ukraine has exposed a once unthinkable divergence between Washington and key Middle East allies Saudi Arabia and the UAE, the oil giants that are increasingly independent on the international stage.

The wealthy Gulf nations, which host U.S. forces and have dependably backed Washington for decades, have notably refrained from supporting President Joe Biden's administration as it tries to choke Moscow's lifelines, from energy to diplomacy.

Two weeks into its war in Ukraine, Russia has achieved less and struggled more than anticipated at the outset of the biggest land conflict in Europe since World War II. But the invading force of more than 150,000 troops retains large and possibly decisive advantages in firepower as they bear down on key cities.

Moscow's main objective — toppling the Kyiv government and replacing it with Kremlin-friendly leadership — remains elusive, and its overall offensive has been slowed by an array of failings, including a lack of coordination between air and ground forces and an inability to fully dominate Ukraine's skies.

Even though Russia has lost influence and friends since the collapse of the Soviet empire in 1989, the nuclear superpower still holds sway over several of its neighbors in Europe and keeps others in an uneasy neutrality.

The Russian invasion of neighboring Ukraine and the humanitarian tragedy it provoked over the past two weeks have raised a Western outcry of heartfelt support and spawned calls for a fundamental rethink of how the geopolitical map of Europe should be redrawn in the future.

Thirty-one foreign ambassadors to Lebanon have co-authored an op-ed on the occasion of the International Women’s Day, entitled "Climate Justice Requires Gender Justice: a Call to Action for Leaders in Lebanon This International Women’s Day".

Below is the full text of the op-ed as received by Naharnet:

Wrangling over the Ukraine war has showed deep divisions in Lebanon and in the Middle East, where Moscow has embedded itself as a key player in recent years, making powerful friends among state and non-state actors while America's influence waned.

Hizbullah has railed against the government's condemnation of Russia's attack on Ukraine, calling for neutrality, after an unusually blunt Foreign Ministry statement caused an uproar and upset the Russians, forcing the minister to clarify that Lebanon did not intend to take sides and would remain neutral.

With his surprise visit to Moscow on Saturday, Israeli Prime Minister Naftali Bennett is assuming the unlikely role of mediator between Russia and Ukraine.

Bennett, who has helmed the country for less than a year and is largely untested on the world stage, positioned Israel in an uncomfortable middle ground between Russia and Ukraine in the lead up to the war, creating a launching pad from which to emerge as a player in diplomatic efforts.
