The development and modernization OF THE PEOPLE make it a civilization, dickhead!
NOT the destruction of some buildings and bridges.
Need examples?

Would destroying these homes and bridges be the destruction of the Somali "civilization"?
Of course not! The PEOPLE were an undeveloped, backward country BEFORE their destruction and they'd remain an undeveloped backward country AFTER they were destroyed! That's because the PEOPLE make a country either civilized or uncivilized, not a bridge or a structure!
And since Trump chose not to make good on his threat and instead impose the blockade that strangles their economy without destroying any more of Iran, you should be very happy, but instead you're still a cranky ****** over it!
