It seems that some world leaders don't learn from the mistakes of their counterparts. It was in Moscow G8 Summit that PM Blair and President Bush were overheard speaking about Hezbollah derogatively. In a similar incident, Russia's President Vladimir Putin has been overheard joking about the virility of his Israeli counterpart, who is accused of multiple rape.
Mr Putin as a former member of the KGB must be aware that whatever a prominent personality does is overwatched. This reminds of a statement by former Soviet President Gorbatchev in which he said that when he had to talk in private to his wife they went to the garden because inside their official house was wiretapped.
Concerning the joke it can be read both ways. I see that Putin was joking at the Israeli President himself since he uses his might in sex rather in something else, abusing his authority and the weakness of his victims. Whatever, political leaders are expected to be tact in their moves. As celebrities the world press is ready to catch any mild bluff by them to make of it a scoop and a hot debate.
After all Putin wasn’t speaking officially behind a microphone for the whole world to listen. As a person having a personal chat he is free to have his say. No one has the right to interfere with him even contributors to BBC WHYS like you and me.
