Count on Bomb Attacks for U.S.

According to the FBI, more than 88 percent of terrorist attacks in the United States have been explosive or incendiary bomb attacks.

If the past has been any type of indicator and the types of attacks being seen in the UK, Spain and elsewhere are indicators -- we can expect that terrorist attacks on American soil will be bomb attacks. Look for suicide bombers targeting citizens and truck/car bombs targeting facilities, infrastructure and symbolic icons.
