To answer this question, I am going straight to the earliest first-hand eyewitness information that tells us what the first Christians thought about this. In the 30s of the first century, did they believe Jesus was a violent nationalistic revolutionary zealot?
The eyewitness is of course Paul, and the clue is right here in his own words:
On the contrary, in Maccabees (the earliest known use of the word “Judaism”) IOUDAISMOS is not a religion per se; but rather that "Judaism" is a broader agenda to which Israelites may, or may not, be loyal.
So, 2 Maccabees 8:1-5 characterises “Judaism” as a reaction to the profaning of the temple, the destruction of Jerusalem, the oppression of the people and blasphemies against God’s name.
And so, in some of his last known words, Paul shows how he has left his past behind him, writing these words:
'Bless those who persecute you; bless and do not curse. Rejoice with those who rejoice; mourn with those who mourn. Live in harmony with one another. Do not be proud, but be willing to associate with people of low position. Do not be conceited.
Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everyone. If it is possible, as far as it depends on you, live at peace with everyone.'
And if you turn to the gospels, you will find words like those quoted from the mouth of Jesus. Because that is the side that Paul had gone over to.
