Look at a map and answer this question. Crimea lies within what country? If it is Ukranian territory, Russia has no more claim to what goes on in that territory that it has with Alaska.
Peacefull nations can and do own nuclear weapons (US, Uk, Germany, etc)
The internal laws of one nation are not the business of another nation. Russia has no more right to alter the laws of Ukraine than it has to alter the laws of China, the US, or Finland.
By that reasoning, Krushchev had no right to simply give Russian Crimea to Ukraine in 1954 …with no consent of the inhabitants….correct?
And Cuba and Venezuela have the right to possess nukes and host Russian bomber bases….correct? Remind me why we are against nukes in Iran? They have rights,too. Israel needs to accept that. Since by your reasoning nuke weapons, other WMD, and military alliances are internal affairs.
And we should not be arming Kurds who aim to alter map borders. Let the Turks invade Syria and end it.
Peaceful countries simply do not do the kinds of things Ukraine was doing or allow their territory to be used for the kinds of purposes that we’re talking about here. You’re basically promulgating a big lie.
