I think 35,000 dollar Shahed drones and Fiber optic basically "Flying hand grenade suicide drones" have changed warfare forever

 If you are wondering why Trump hasn't sent U.S. Troops into Iran it is because Ukraine is killing 30,000 to 35,000 Russian Troops monthly with basically flying hand grenades and fiber optic flying hand grenades which ruthlessly kill ANY Russian Soldiers walking around on the ground. If they see the flying hand grenades they are usually already dead. there is nothing to save their lives from these drones flying directly into them and exploding their bodies into bits.

Now Hezbollah is using these flying hand grenade suicide drones into Israeli soldiers too. You cannot jam electronically a fiber optic flying hand grenade drone either which are presently effective up to 10 miles inside enemy territory with prototypes accurate up to 50 kilometers now too.

So, a fiber optic drone is almost unstoppable from killing soldiers who are walking around anywhere now and when they see this flying hand grenade they are usually already dead within a few seconds because of the speed at which they travel (up to 100 miles per hour).

So, if you are wondering why Trump hasn't sent in troops into Iran because he doesn't want 30,00 to 35,000 of them killed like the Russian soldiers every month from suicide drones picking them off one by one.

Zelensky says it costs him $1000 to kill every Russian Soldier with a Flying Suicide Drone Hand Grenade which is likely very cost effective for the Ukrainians given all present variables.
