[M. Espinola]

Western leaders, especially those in NATO, should be closely monitoring Putin's repeated vicious utilization of energy blackmail as a economic weapon against Moscow's enemies (former communist Russian occupied countries, now free & independent nations) since it's only a matter of time before energy blackmail is replaced by Russian tank divisions, and wholesale civilian slaughter.

NATO needs to make it clear to Putin's Russia aggression shall be met with counter force against dictator Putin's evil empire.

Putin’s repeated vicious utilization of energy blackmail as a economic weapon against Moscow’s enemies ==

What is wrong with using weapon aganst enemies? You do not that? Estonia FIRST started this hostilities so now she should pay the price.
Russia will stop all transit through estonian ports and all trades with her. Soon Estonia will be the dead end of Europe. Russia has no obligations to support the hostile nation with her business.
