The natural conclusion is of course, "no one," and it's pretty easy to see why.
But I'd like to look at the question a bit differently, because that's not the real question. The real question for Christians is "Lord, what would you have me do?"
Also, I don't like the self-righteous sneer embedded in the question asked the first way.
The people closest to Jesus were remarkable for their repeated inability to anticipate what He was going to do and say. This alone should give us pause when making claims of knowing what Jesus would have us do. If Peter and John couldn't figure Him out until much later and after much reflection, then who are you? I make no claim that random or always counterintuitve actions are what Christ wants from us, only that the simple answers sometimes blow up in our faces when contemplating Our Lord. Jesus fed the multitudes and quite sternly admonished the rich to give. But he also criticized Judas for wanting to give money to the poor in a particular way at a particular time. Jesus went with complete nonviolence to His death - almost immediately after beating the moneylenders out of the Temple.
Almost every word that comes out of His mouth is a surprize, in fact. Not what we expected. Jesus, do you want to eat? "I have food of which you know not." "Be perfect." "Whose face is on the coin?"
These things are understandable and explainable in their context, and under the instruction of the Holy Spirit, but they are emphatically not our first guesses of what He would do.
Jesus frequently turned a general question back to an individual answer. "You must be born again" He says to Nicodemus. He admonished the rich young ruler "Sell all your goods and give the money to the poor." When the Pharisees tried to trap Him, He usually told them something about themselves and their own thoughts.
So my first guess is that Jesus might tell many of us, asking about war in Israel, war in Iraq, threats from North Korea "That is not for you to know. You have other work to concern yourself with." Which is hardly what any of us want to hear. Jesus is far more likely to tell us "What happens in the world is unimportant" than "I forbid war." This is reflected in the actions of the first few centuries of the church, when Christians were (much) more likely to see themselves as avoiding the wars of governments because they were called to a higher goal than to preach pacifism. We should not impose our way of seeing things on them.
Jesus didn't go up to any of the rulers of the age and tell them what they should be doing. John the Baptist did, but here's the thing: John didn't give political condemnation, he gave condemnation for the individual acts of Herod. Those personal sins don't appear to have had much to do with any of the political decisions of the age. In the context of oppression, the Baptist finds it more important that the ruler of the people be personally pure than that he act in some political fashion. And Jesus clearly approves generally of the actions of His cousin John.
This was a common OT theme. God seems exceedingly overconcerned with the personal piety of Moses and his own individual sins. The sins of Saul, David, and Solomon are believed to affect the entire nation somehow, though the Scriptures are not very clear exactly how that is.
When we pray for our leaders, we usually go for some variation of praying that they have wisdom. Perhaps we would do better to pray for the personal actions of presidents, Senators, military commanders, that they be righteous in their family and business dealings. How will that help? I dunno, but God seems to like it. He mentions it often.
When Jesus speaks to a Roman soldier, He doesn't hint that maybe the man would find spirituality easier in another profession. He tells him how to do his job justly. Go figure. On the other hand, Christ is clear, even emphatic about not hitting back when attacked. On the other other hand His disciples are still carrying swords around three years into the ministry of the Lord.
It is just to easy to use a phrase like "Prince of Peace," and believe we know what we are talking about while putting an entirely modern spin on the word "peace."
Beware the false dichotomies in these questions. "Oh, so you think Jesus would nuke the Iranians then?" "Are you saying that Jesus wants us all to spend more time making money?"
No, I'm just saying it's never simple, and always requires prayer - sometimes an agony of prayer if you really want the True Answer. Don't even listen to those who would make it simple.
