To send a military flotilla to break a blockade against a closed military zone of another nation is under any legal definition an act of war. Gaza is not an independent state and is not recognized as possessing sovereignty. Under international law, Gaza and its coastal waters fall under the military jurisdiction of Israel. Erdogan is a cheap political trickster who is way out of his league. I am sure that the Turkish military has no intention of pulling off this stunt, knowing full well that a military altercation with Israel - and perhaps the United States - will not go well for them.
