The government of 1936 has no legitimation nowadays, or at least has the same as Franco's governments or medieval governments, that is, nothing.

In 1936 that government tolerated and even praised burning of churches, prosecution of the political opposition and even freed everyone in prison. The last republican government reached power by a coup d'etat. Would USA recognize pre-independence governments as a source of legitimation for its laws???

We only recognize as the source of legitimation the Constitution of 1978 which was agreed by the majority of the spaniards (including basques) as a framework of good convivence. Autonomy was not the means to achieve independence, but the means to achieve a good status in which everyone could have its claimings satisfied to a point.

You are forgetting that more than half of the basques are more than satisfied with the current status.

It is a minority who wants to impose other status by violent means. And current basque government is just breaking the law to satisfy that minority.
