But only if man lets him be.
Arminians believe their will can over ride the "Arminian belief "that God wants all men without exception saved
They believe that every man can freely choose to do Gods "perfect will" or His "permissive will" or to do what is contrary to Gods will
So God is only sovereign if man allows it (which makes one wonder who is REALLY sovereign)
Man can choose whether or not to sin, and the fact that a man can choose to sin has no effect on the sovereignity of God. After all, the sovereign can impose consequences for disobedience. So you see, man can have a free will and God still be sovereign. God is God, and God is sovereign, and the sovereign does not submit his will to his the will of his kingdom. Quite the contrary, if the people do not submit their will to the sovereign, there is a severe price to be paid.
Contrary to what you may think, most Arminians believe this.
