The Qatari Emir, Sheikh Tamim bin Hamad Al Thani, played a key role in convincing the United States against a military solution to the crisis over Iran's nuclear program, US President Donald Trump said.

"Iran is very lucky to have the emir because he's actually fighting for them. He doesn't want us to do a vicious blow to Iran. He says, ‘You can make a deal. You can make a deal,’'" Trump said during a meeting with US and Qatari business leaders in Doha.

According to Trump, former US President Joe Biden set the entire Middle East on fire, then just walked away after spending $10 trillion on conflicts.

Biden was very bad, he is the worst president the US has ever had, a completely incompetent person, the incumbent US president believes.
