This is starting to remind me of the July Crisis, where Franz Ferdinand was assassinated June 28 (by assassins supported by Serbia).
And Austria dithered for a month and then attacked Serbia on July 28.
This could easily be the spark to ignite WW3. If Hezbollah joins in it’s on like donkey kong. That’s why many Western countries are trying to discourage Israel from any ground activities in Gaza. If they go in it’s almost certain Hezbollah will react and that could incite Jihad in the neighboring Arab countries which could easily get out of control.
