In this video Gonzalo Lira says there is no blockade in the black sea by Russia. If you watch the video you might realize he's mostly correct. I've posted before that Russia wouldn't have a problem with grain leaving by ships from Odessa. The one point in which Gonzalo Lira did not mention was these massive ships need a lot of oil to run them, and I don't thinks Ukraine has any to spare. In the end he's correct, Russia looks like the bad guy. Also Ukraine mined the black sea making it dangerous for shipping. But yet again, Ukraine accused Russia of mining it.
