In an interesting turn of events, NATO refused to pledge more support to Ukraine despite the recent events dealing with the Ukrainian ships and sailors being seized by Russia.  This seems to be due to the fact that the alliance seems to be extremely hesitant to escalate the situation. Ukraine was hoping for NATO to deploy ships into the Sea of Avov in order to protect Ukrainian rights to navigate but this will not be happening.

This may cause some issues in the case of alliances between Ukraine and NATO but considering that Ukraine is extremely reliant on NATO for its security at the moment, that should be fine. However this does not take any real action against Russia and considering Russia’s history, they could take it as incentive to take further action. On the other hand, not escalating the conflict into a full blown war is always a positive thing and it should be recognized.
