Geopolitics

"So why now?
Iran could be weeks away from developing a nuclear weapon
No Hamas threat from the south
No Hezbollah threat from the north
No Assad threat from the northeast
No Syrian forces to hinder Israel
Ability to fly over Syria and refuel
Full visibility atop Mt Hermon
Degraded Iranian capabilities
Russia too weak to help
Window of opportunity: Netanyahu has 16 months before the next elections
Window of opportunity: Trump is in power"
