US withdrawal from Syria would shake up situation

A decision to withdraw all US troops from Syria would greatly change the situation in the war-ravaged country, said analysts, and they expressed doubt as to whether the troops can be fully pulled back as the United States president has claimed.

US President Donald Trump said he has decided to pull all 2,000 US troops out of Syria after he declared on Wednesday a victory over Islamic State.

"We've won against ISIS," Trump said in a short video posted on Twitter. "We've beaten them, and we've beaten them badly. We've taken back the land, and now it's time for our troops to come back home."
