Obviously a Palestinian state cannot be established while Hamas exists. If in future Hamas does not exist then certainly he supports a Palestinian state, and today he can work towards that goal.
As Obama stated:
"Afterwards, he (Netanyahu) pointed out that he didn't say 'never,' but that there would be a series of conditions in which a Palestinian state could potentially be created," Obama said. "But, of course, the conditions were such that they would be impossible to meet any time soon."
You are also adding conditions that make it impossible to establish a two state solution, just as Netanyahu does.
That is not supporting the two state solution.
