why believe the missiles can hit London claim when that also has no evidence presented. .
I think with regard to that claim people need to look at the big picture and not just make a knee jerk reaction either way based on "cos the IDF says..." they need to look at what's in the public domain..
The Iranians have a mature ballistics missile industry but fortunately as far as we know none of their military types of missiles has the range to reach western europe..
However the Iranians have demonstrated the capability to launch satellites using their own indigenous launchers, which like it or not, objectively, according to the science and engineering, means if they wanted to they in theory might be able to reach western europe with something....
Problem they'd have in the current conflict would be erecting and fuelling a launcher without it being detected and attacked, also we don't know what weight of payload could be carried, and we don't know if the Iranians have solved the problems with re-entry heating at high velocities...
To cut to the chase I suspect if you asked intelligence specialist/analyst if the Iranians, if so minded, could launch something that could reach the UK they'd say something like .."highly highly unlikely, but I can't say the probability is absolutely zero".
