Ukraine is currently the only country that can defeat Russia. NATO countries are bound up in the treaty; all they can do is gear up to face Russia's re-militarized economy. The time to nip it in the bud was more than a year ago, before Putin had a chance to consolidate his grip over the country.
Proper leadership is to stand up for what's right, and to be ready to escalate beyond your opponent. However, the ethical principles that underpin "rightness" are missing in the majority of our political leaders.
