Khashoggi killing was a test case for Biden, who had promised to penalize the Saudi crown prince, but his administration exempted him. This raises serious questions about his proclamation of upholding human rights.
In his election campaign, Biden pledged to reverse Trump's policies and make fundamental changes in US foreign policy. Some observers doubt he can make any significant difference. There is hardly any difference between Democrats and Republicans when it comes to foreign policy of the United States. The conservative-liberal divide appears more significant when it comes to domestic policies.
Biden administration has imposed a ban on some Saudi officials for the Khashoggi killing. But it was not extended to bin Salman. Many believe Biden is not serious when he is talking about human rights, especially with reference to Saudi Arabia.
It may not be wrong to say human rights issues never determine the US foreign policy, it is just a propaganda tools. The mantra is used against hostile states and not the friendly ones. Saudi Arabia is still a US ally and the US does not want to undermine its relations with Riyadh.
It was the United States that pulled out of JCPOA unilaterally in 2018, but Biden administration is not taking concrete steps to rejoin and lifting the sanctions imposed on Iran unilaterally. Biden wants to use the existing sanctions to force Iran to agree to talks on other issues.
Biden policies towards Iran seem even more confusing because he is trying to keep Trump's sanctions in place as well as talking about diplomacy. He wants to force Iran to make some basic concessions, such as reducing its missile program and changing its regional strategy. Biden wants to achieve these goals through diplomacy. Trump, too, wanted to talk to Iran, provided Tehran agreed to his conditions.
Presidents of United States are generally more receptive to Israeli Mantra. Israel has been advising the US not to return to the JCPOA without significant concessions from Tehran. Some hardliners in Israel still hope to trigger a military confrontation between Iran and the United States.
Israel’s military chief has warned of a new plan to strike Iran's nuclear facilities. Some Iraqi groups have claimed that Israel is behind some provocative attacks on US military bases in the Iraqi territory. All this is aimed at derailing the process of revival of JCPOA.
