"The only thing necessary for the triumph of evil is for good men to do nothing"
And yes, it's evil, and no, it has nothing to do with their border security, that's a ridiculous suggestion, in the same vein, you would be ok with Russia annexing Poland, Lithuania, Finland or Estonia because they are armed and bordering Russia.
As for the whataboutism, that wasn't the subject.
No, it's ridiculous.
Russian economic development through war doesn't save Russian babies, it will kill them.
Ukraine's attempts to prepare against invasion do not justify said invasion.
