Iranians may be dumb, but they’re not stupid. They know what Pelosi’s doing, and they will not mistake her actions for the OFFICIAL American position. They’ll try to play the Dems against the Republicans, as they always have, and the media may even buy it, but when it comes down to it, the Iranians know what the policy of the US actually is.
Iranians know how to undermine America.
They watch TV. They know a speaker going to Syria while the White House is disapproving is an evidence of division in the US.
Iran’s strategy : always use the division of your enemy.
