Besides, your actual risk of dying in a terrorist attack is nowhere close to 1% / year.
It's actually 0% per lifetime, rounded to many decimal places.
Statists and authoritarians like to overstate external threats as an excuse to consolidate & expand state authority internally. It's an old and common tactic.
Grow some balls. I'll take a 1% chance of dying to terrorists every year over an Orwellian government that passively intercepts everyone's communications.
