After WWI, the Palestinians were generally opposed to the idea of a Jewish state on the land that the Palestinians thought of as their own. When the Zionist Jews first came to Palestine, the Palestinians did not particularly oppose them.  However, as it became clear that the Zionists were going to try to set up a large area (and potentially even a state) for themselves, the Palestinians came to oppose the Zionists vehemently and even violently.  The Palestinians did not have a solution of their own for "the Jewish problem."  Rather, they simply did not want the solution to involve taking land that they thought was theirs.  Outside of that, they had little in the way of opinion on the Jewish problem.
