No need to give in, if they can just tell him his whole Black Sea fleet will be immediately sunk if he tries to stop any ship with grain from Ukrainian ports. Putin only understands such language, nothing else. Let's say Ukraine will get at least 20-50 Harpoons and NSMs with option to resupply. Putin will immediately shut up about the blockade because his ships won't have anywhere to hide. Problem solved. > Not to mention that sanctions hadn't made any significant dent anyway. Russian economy is booming unfortunately. This is false. Sanctions are biting Putin clearly strong enough if he is using blackmailing with famine for their lifting. If anything, sanctions have to become stronger. Oil and gas trade with Russia has to be banned, since it's the main source of funding the war for Putin.
