President Joe Biden confused Palestinian militant group Hamas with Hezbollah while announcing a ceasefire to the Israel-Hamas war on Wednesday.

President Biden had just one word to say on whether he's concerned about Hamas regrouping after a ceasefire deal was finalized on Sunday.

In a brief address on his last full day as president, Joe Biden hailed the ceasefire and hostage release in Gaza and predicted Hamas would not regain power. He also defended his support for Israel in the 15 months since Hamas’ Oct.

In another gaffe, Joe Biden mistakenly refers to Hamas as Hezbollah while announcing Israel-Hamas ceasefire deal brokered by the US, Egypt, and Qatar.

Netanyahu's office said Hamas had "reneged on parts of the agreement reached with the mediators and Israel in an effort to extort last-minute concessions."

Both the Trump and Biden administrations have publicly claimed credit for pushing the agreement over the line.

President Joe Biden said goodbye Wednesday night, telling the American people that serving as president has been “the highest honor of my life” but warning that dangers on the horizon pose a serious threat to democracy.

One of the famous Senator Amy Klobuchar during a recent development eventually revealed that what kind of conversations took place between the US President Donald Trump and former US President Joe Biden when they shared the limousine ride to the US Capitol for the swearing in of Donald Trump.

President Joe Biden also issued preemptive pardons on Monday ... the ceasefire will lead to a lasting peace between Israel and Hamas as well as the role Trump and Biden played in negotiations.

The end of the 15-month conflict in Gaza is in sight, with Hamas and Israeli negotiators reaching a ceasefire agreement on Wednesday. The phased deal, expected to take effect on Sunday, January 19, will see the Hamas swapping hostages with imprisoned Palestinians in Israel.

Historians say it will take years to fully assess Joe Biden's legacy, but several spoke to ABC News to offer a glimpse of their view on his presidency.
