It would be good to hear how many that were in favor of ending the war because it's the right thing to do. Because it's unjust. Because it's an invasion of a sovereign nation. Not just "Because the sanctions make my butter too expensive".
The difference being that if the former number is over 50% that might mean the people would be for change, for new leadership and direction. If the latter is above 50 that just means people want cheaper butter. Perhaps wait a bit and try invading later. Or invade some weaker nation.
