I think what your question touches on is the need to think about how we frame national security concerns. You're right; after 2001, in the wake of the 9/11 tragedy, the government put into place a national security strategy. Today, yes, of course we continue to be vigilant against anti-terrorism, but we also have to think about foreign interference.
