Israeli interior minister Eli Yishai has banned Günter Grass from entering Israel.
That'll teach him!
It's a basic thing for a country to be able to decide who can and can't enter the country and an activist against that country seems like a good candidate for being banned, so I really don't see any problem with this.
So, basically what you are saying is that sovereign governments have the right to act stupid.
This is of course true.
(Just like you have the right to write stupid poems in a free society, of course. 
)
Yes, but I don't think this actually was a stupid decision, and I would have done the same if I were in Yishai's place, Israel shouldn't be letting activists against itself in to the country.
The problem is than Grass isn't an activist against Israel, but an activist against current policies of Israel government. He just protested a policy of Israeli government, he didn't called to the destruction of it.
It is like if Bush banned entry in the USA to anybody not supporting Iraq war.
It's attacking freedom of mind and it shouldn't happen in a democracy.
If the government continue like that, it shouldn't be surprised when the list of its allies will decrease.
