The purpose of NATO is mutual defense of NATO members.

Is Ukraine a NATO member? No.
Does Ukraine want to be a NATO member? No. They dropped that goal in about 2010.

How interested in Ukraine should NATO be? Not at all.
NATO is a trouble-maker.

Does Ukraine want to be a NATO member? No. They dropped that goal in about 2010.

Ukraine's Verkhovna Rada parliament voted 226 to 224 not to be in NATO in 2010.

Given the turn of events I don't think it would be too hard to see a two vote swing to the pro NATO side.
