US National Security Adviser Jake Sullivan said on Monday that his country will deal with all groups in Syria, and welcomed the statements of the armed opposition that overthrew the regime of ousted President Bashar al-Assad.

Sullivan said in an interview with CBS that the statements issued by what he described as rebel groups in Syria, including those classified as terrorists, are good.

He was referring to Hayat Tahrir al-Sham, led by Ahmad al-Sharaa (al-Jolani), which led the “Deterrence of Aggression” operation and led to the overthrow of the regime in just 12 days.

The leaders of the Syrian opposition's military operations department, led by Al-Shara, pledged to guarantee the security and rights of all components of the Syrian people.

The US National Security Advisor said that his country did not directly participate in the attack that brought the armed opposition to power in Syria, nor did it support it or take part in it.

But he made clear that Washington was part of a broad regional and international effort to weaken Assad's backers.

Better than a lion

Sullivan said anything in Syria was better than what he called a "brutal regime" that had destroyed its people for 50 years.

He considered that there is an opportunity to build something much better in the future in this country.

The US official continued that the question now is what will the Syrian factions do to achieve a better future for their country? He spoke about the risks of the possible return of extremism and terrorism in Syria, saying that Washington is dealing with these risks immediately, as in the air strikes ordered by President Joe Biden against the Islamic State.

For his part, US National Security Council Communications Coordinator John Kirby said that Washington will work to explore ways to communicate with the groups that took control of Damascus.

"We are now in a period of uncertainty and actions will determine our confidence in the leader of Hay'at Tahrir al-Sham," Kirby added in statements to CNN.

A senior American official said yesterday that his country (Washington) intends to deal with Hay'at Tahrir al-Sham, taking its interests into consideration.

On the same day, outgoing US President Joe Biden said the United States would work with "all Syrian groups" within the framework of the United Nations to ensure a political transition after the fall of Bashar al-Assad's regime.
