This is the same Hezbollah is an Iranian-sponsored group which had helped the Syrian forces fight agaisnt American/Saudi, Gulf State proxy Jihadists, of course i wasn't surprised when they branded Hezbollah as a terrorist group.
It shows how you Americans are getting desperate in the region and branding groups who are fighting your own proxies in the region is another example of that.
Whats the US agenda in that region again? FREEDOM AND DEMOCRACY? don't make me laugh. Its all about dominance and control of the regions and supplies of resources.
Which you dont want Iran to have nor to compete with Saudi Arabia. Having a puppet in Iran would be better for you so the Iranian puppet can easily bend over to its knees to the Sunni dominated middle east.
