Sorry to disappoint you, but there are no "extreme doubts" regarding this quote.
The quote is attributed to Ariel Sharon, former Prime Minister of Israel. It was reportedly said in 1998, as cited in various sources, including a 2001 article by Israeli historian Benny Morris in The Guardian. The exact context and wording may vary slightly across references, but Sharon is consistently credited with this statement.
I have found no contradictory attributions. If you have - please provide links to sources where this so called "extreme doubt" is expressed.
You need to learn to provide supported counter-arguments.
