What happened in the past has no relevant to the present because as someone said, diplomatic relation has its up and down.
For example, both Pakistan and USSR were enemies is now enjoy stable relationship. So what happened in the past may not mean much in the present or the future.
But what happens is the pattern which cannot be ignored given Ukraine is about to be used like trash and thrown away much like previous examples in the past. The pattern with western navy continues to be predictable as ever. And present Ukraine is about to face the same reality proves why the pattern cannot be ignored given the reality of navy.
