The concern regarding the debate was that when it came to Syria, that Clinton would introduce a 'no fly zone'. A 'no-fly zone' means you destroy the enemy's airforce, radar defence systems, rocket systems, telecommunications systems, train stations, highways, and any government or non government building that could be used to provide air defence, thus mosques, hospitals and schools. This is what the US imposed no-fly zone did to Iraq, and to Libya. As ISIS doesn't have an airforce in any form, that having a 'no-fly' zone is simply madness and would allow ISIS to move about freely on the ground. The fact that she still sees war with Syria, and Russia, as a good outcome...and a no-fly zone IS real war, and that she'll persuade the Russians and Syrians to accept it...including destruction of the Syrian Government airforce, and the Russian missile bases just indicates how mad and deranged her real views are.
