The thing is that we are always told there is evidence, like for sure, trust us:

Assad bombed his own people

The Russians hacked the election (a very broad statement, like “let’s believe in evolution”)

North Korea hacked SONY

All at very convenient times for our moves abroad and totally nonsensical from the point of view of motivation of the ones doing it (like Assad)

It’s like they don’t even try anymore. They just say “17 intelligence agencies all concur” with each other.
