Following a string of recent successes, Syria's government is in a dominant position as the Syrian civil war transitions to a new phase. Meanwhile, the two largest outside powers involved in the conflict — the United States and Russia — are looking to make an exit as their primary foes lose ground. But even as the war appears to be winding down for some, it's beginning to ramp up for one key player: Israel. The increased Israeli activity in Syria stems from Israel's priorities in the Levant, which differ greatly from those of the United States and Russia. Washington's concerns center mainly on the threat posed by violent extremist groups, while Russia is working to secure the Syrian government and Moscow's own position in Syria.
