Yes, I consider Obama to also be to blame somewhat. But in practice, the situation with the 2014 invasion was a lot more complex to respond to. Russia quite successfully obscured their involvement in the first couple of days...all signs pointed to Russia but they denied involvement and the little green men wore no Russian insignia, so it could have just as easily been framed as internal separatist activity, which was the Russian intent. It actually took a couple of weeks before it was crystal clear that Russia was behind everything. By then, Crimea was already occupied.

The war in Donbas was only a little bit more clear. Even though Russia's fingerprints were all over every action there, there was also no doubt that there was significant Ukrainian separatist activity, and even the most resolute of allies will hesitate to defend their allies from separatist activity.

With Biden, we saw the buildup, knew it was going to happen, and had been warning Ukraine that it was going to happen. We saw it for what it was on day one without any equivocation. We just did nothing about it.
