France may already be fighting as of Jan 30th, in World War IV, cause this implicates several nation-states and France is just hateful when they get pissed.
They could have taken the fact that the plans were for a simultaneous attack on Rome, Paris, London,- that is, European Capital Cities - as an explicit act of war and also Declaration of War in some traditions. Using multiple diplomatic passports and diplomatic immunity - this is beyond a simple screw up.
I don't think this can be stopped from going extremely hot in a very short time because both Hamas and Hezbollah have been caught prepping for some sort of attack.
Don’t the realize they’re gonna get their a$$es handed to them?
