Yes, that is all that can be done, unless we can secretly get to their nuclear weapons or prevent them from using them on us some other way. It would take an incredibly drastic situation for us to go to war with a nuclear country. It would have to be something like a situation where a country announces that they are in fact going to nuke us.
Here is a case where preventing death takes precedence over promoting freedom. I'm guessing the entire disagreement lies in the degree to which innocent lives can be sacrificed for the greater good.

My position on this matter is that the only life we have the right to sacrifice is our own. We have no right to decide that it is just to kill one group of innocents to save another, because we cannot judge the value of an innocent life. Those who initiate wars make the choice of sacrificing innocents to serve others, and are in the wrong.

It would be so easy to launch wars and topple the world's dictators, but to do so assumes that we have the authority to sacrifice those who may not be willing to die for our cause.

If an oppressed people wants to topple their tyrannical government, we should by all means support them, because they are the only ones with the right to sacrifice their lives for that cause. We can't make that choice for them.
