Choppy times in U.S.-Israeli relations

(Reuters) - A rift between President Joe Biden and Israeli Prime Minister Benjamin Netanyahu over Gaza red lines has set up a potential showdown between the two leaders, raising questions about whether the U.S. might restrict military aid if Israel goes ahead with a ground offensive in the south of the enclave.

The United States has been a staunch ally of Israel since President Harry Truman became the first world leader to recognize the newly established state in 1948.

But strains have emerged in the normally solid ties over the decades. Here are milestones:

Washington withholds $10 billion in loan guarantees sought by Israel to absorb the immigration of Soviet Jews, piling pressure on Prime Minister Yitzhak Shamir to attend the Madrid peace conference. Bush cites the best interests of the peace process in justifying the postponement, and says he will not grant the guarantees unless Israel freezes settlement building.

1992

Bush approves Israel's loan guarantees request after Prime Minister Yitzhak Rabin offers a limited curtailment of settlement building.

1993

President Bill Clinton hosts a handshake between Rabin and Palestinian leader Yasser Arafat at the signing of a Declaration of Principles on interim Palestinian self-government.

1998

2004

2015 

Obama says the international community does not believe that Israel is serious about a two-state solution.

2016

Obama, in the final weeks of his presidency, allowed a U.N. Security Council resolution condemning Israeli settlement building to be adopted by withholding the U.S. veto. It breaks with a history of U.S. shielding Israel at the U.N.

2017

Reversing decades of U.S. policy, President Donald Trump recognises Jerusalem as Israel’s capital. The new U.S. embassy opens in 2018.

2019

March 9 - Biden says Israel’s threatened invasion of Rafah would be his “red line” for Netanyahu but then backtracks, saying there is no red line and "I’m never going to leave Israel." Biden says his message to Netanyahu about civilian casualties is that he is "hurting Israel more than helping" by acting in a way "contrary to what Israel stands for."

March 12 - Netanyahu says that Israel would press forward with its military campaign into Rafah.
