Yes it is suicide bombing to be sure, but I believe she meant that the 9-11 attack was like a one-time highly planned attack vs. the constant everyday "man walks into nightclub and blows self up, 8 killed" type attacks that Israel is afflicted with. However, I dont think that we will ever see those type of attacks on the same scale here for a number of reasons. It wouldnt surprise me if there were a few of that type over the next few years though unfortunately.
