Yeah these are real, actionable threats. The world should be banding together in a military alliance against the US at this point because they are by far the biggest threat.
Maybe Trump will pull out of NATO first, at the end of the day it's not like Europe is going to stop being dependent on the US military industry if that happens. If anything, without NATO there's probably going to be a panic leading to Europe to arm more which will translate to more contracts for US companies.
