How come there is little discussion on the Samson Option and how it might be compelling Western governments to support Israel?

The Samson Option refers to an Israeli military strategy where Israel will launch their nuclear weapons if they are under existential threat. According to the article, the threat of the Samson Option has already been used to compel the USA to give aid to Israel at least once, in 1973.

With a lot of discussion online from Westerners being displeased that their governments are supporting Israel, why do so few people talk about the Samson Option?

• Is the Samson Option still the main compelling force for Western governments to support Israel?
• Does nobody take the Samson Option seriously anymore?
• Or are there deliberate efforts to make sure people are unaware of the Samson Option?
