My prediction is a mass casualty false flag event that will be blamed on conservatives.
Victoria Nuland destabilized the Ukraine and set the table for the Ukraine war. She orchestrated a coup. Hillary Clinton set the Middle East on Fire. Biden is a de-facto ally of Iran and thus gave them money and removed sanctions. Thus Iran can now finance terror in the Middle East.
Compared to what they have done, a mass casualty event is a rather minor thing. These people are evil.
It would be easy to have somebody take out Biden, who is expendable, and blame it on MAGA.
