>> would you hope israel got rid of its chemical weapons? >> tarik hazziz told me after my second mission in 1991. he said, dr. david, we didn't think you're not behaving like a u.n. inspector we expected. you go into these agreements thinking one thing will happen, and something else happens. and we're going in, i hope if we go in, to seriously seize control of these weapons with the ultimate purpose of destroying them. i can guarantee you today there are a lot in the syrian military that aren't committed to that scenario. >> how long would that take by the way? the assessment, securing and destruction? how long is that? >> it would take years. >> just break it down. >> it's going to take decades if you go to destruction. >> the assessment and securing. how long do you think that would take?
