Those who advocate no fly zone are basically advocating war with Russia. No fly zone only work against small nations like Iraq. Its not going to work against Russia. You going to threaten them and they’ll call your bluff and move in anyway and an air war starts with Russia. ISIS are goign to flee and be protected by US air cover. How does it feel being ISIS’s air force?
If they want a shooting war with Russia, that’s the way to do it. It will be us that gets shot at first. The Russians have a super-power sized chip on their shoulder. If we play their game and shooting starts, then where does it stop? The Baltic states, the rest of the Ukraine? The immediate transfer of advanced weapons to Iran with the “advisors” to operate them. They could shut down the Straits of Hormuz before we could decide on the arrangement of flags as an associates peace summit. Putin is dangerous, because he knows we won’t stop him. The only way to do it without shooting is to make moves that threaten their economic interests. They like selling natural gas to Europe. We should threaten to get into that business.
