Mr. president hasn't finished his term yet, and hasn't formally stepped down. So I am asking Russia to return him to Syria, else he'll not be able to fulfill his duties. According to him Russia has coerced him into fleeing the country and that's not cool.
Plus it's Christmas season and Russia is ruining the holiday for Syrians by stealing a very special Christmas ornament the country would've had.
Russia has its two ports which Assad signed away for the next gazillion years and Assad himself, who's a property of Syria, and should be returned to be dealt with accordingly.
The real concern is Iran, Israel, and the US. Iran is currently using the desperate criminals Assad left behind to cause instability and should be the top priority of the new government.
Turkey is an alley of the new Syrian government. You can compare it to what Russia was for the regime, but not committing war crimes against most of the population.
Or even better, just after they close the bathroom door.
