most weapons destroy shit in an area of 100square meter the most but taking the size of a country you need a million bombs or rockets to cause significant damage

why is nobody building and/or using largerweapons.

we can build weapons that fly 300km maybe 1000 kilometer the most, we can hit a plane in the sky but look how small a plane is

where are the weapons that level everything on a radius of 50square miles
why isnt shit like that being built

even the 9/11 attack they had a hard time to level these buildings and the world trade center is a small part of New york

next question, what would be needed to build weapons that can literally destroy a cty like new york or london besides nuclear bombs
