One big difference is that the US has been led by four different people since 2000 instead of one. Another big difference is that it's legal for Americans to insult political leaders, wish bad things upon them, or demand an end to their stupid wars.

If you weren't aware of these differences, I'd encourage you to radically change your media diet; there are unfortunately many outlets which find it advantageous to exaggerate how bad the US is and deemphasize how bad dictatorships are. (Some are paid Russian propaganda, I've seen a shocking number of people send me RT links as though they're a legitimate news source.)
