The left in the US follows the same progression as the left in Europe:

• Regular protests
• Violent protests
• Attacks against state infrastructure (usually railways, power distribution, police and military vehicles) <- the US is here, that's also the point where politicians start to decide on which side they are on, thus leading to the next steps
• Vandalism of homes of politicians
• Burning down cars of politicians
• Violent attacks on private citizens accused of wrongthink
• Violent attacks on politicians <- Germany is already here
