What measures are in place to prevent a car of truck bomb from killing 100s and destroying large buildings?

Question

Are we in the U.S.A. fairly safe from such disasters like the 1995 Oklahoma city bombing or even possibly a succesful version of the 1993 WTC Bombing?

Answer 1

none what's however.

Answer 2

It can be done all that people require is to call up army engineers and destroy most cars in cities and a vote for The Green Party as it would do this to stop Global Warming.Also to stop hi jackings demolition of major airports.

Answer 3

Why would you ask that?  Are you seeking information to help the terrorists?

My answer is: we have thwarted a number of these types of pending attacks in the last few years and will continue to fight terrorism.

Answer 4

No, I don't think we truly are.  I think our system of intelligence is improved, but as far as someone just deciding to do such a thing, the work place shootings and other random events tell us that while we may have tapped into identified terrorist information, true danger comes from that which is not identified,
