Biden's statement is ridiculous, as after the agreement was already broken the US had a range of choices to go for. The whole word saw how well following this broken agreement went.
You mean the mobilization of the thousands fleeing Russia to avoid fighting? What's left won't make a difference. Looks far more likely to me that Vlad The Bad is more likely to be targeted by 'friendly' fire.
This is also what Trump said (after the invasion started):

Your story predated the invasion - Trump did not approve of the invasion.
