Is this sentence correct?

"Post-Soviet Russia has long hesitated before definitively recognizing the frontiers with its new neighbors"

The recognition comes after the hesitation; therefore, the time period for the latter is finished. Plus Russia has NOT been hesitating for some time now.

Isn't it better to say:

"Post-Soviet Russia had long hesitated before definitively recognizing the frontiers with its new neighbors"?

OR

"Post-Soviet Russia hesitated for a long time before definitively recognizing the frontiers with its new neighbors"
