Syria doesn't need the Golan. The Assad regime would only use sovereignty of this strategically important area to brutalize its inhabitants and to stage attacks on Northern Israel, like it did prior to 1967. Under Israeli rule and control it is the most tranquil and developed part of Syria. The human rights of its inhabitants are respected, something that cannot be said of the rest of Syria. The Golan is in good hands now, no reason to return it to international pariah state Syria.
