i am not sure that this makes sense

instead of daying "watch out for the eiffel tower"
how about not telling anyone what they learned and put about 200,000 undercover soldiers all around the eiffel tower and tower of london etc?

then you like actually catch them

iknwo that this is a strange tactic to use- actually capturing or killing terrorists that are about to attack

instead? a warning?

we have the worst counter attqck countries in theworld or something
