Based on my research, I need to clarify the timeline of events regarding Netanyahu's speech and the death rumors.

Analysis of the Claim:

• Death rumors about Benjamin Netanyahu began circulating in early March 2026¹, before his March 12 address. Iranian state media and pro-regime accounts had been pushing reports about his death since the conflict began².
• On March 12, 2026, Netanyahu gave a press conference/address on national television providing an update on the Iran war³⁴. This was his first press conference since the U.S. and Israel attacked Iran³.
• The death rumors intensified after the March 12 address, with social media users claiming the video was AI-generated due to an alleged "six fingers" frame³².
• Data shows "Netanyahu is dead" appeared 218,580 times across social media from March 9-17, peaking after the March 12 speech⁵.
• Netanyahu posted a "proof of life" video on March 16 (Sunday) to debunk the rumors after they had gained significant traction⁶⁷².

Conclusion:

The claim is FALSE. Netanyahu gave his speech on national television on March 12, 2026, but the death rumors had already been circulating in early March before this address. The rumors actually gained traction after his March 12 speech, not before it. The speech intensified the speculation rather than preceding it.

Overall validity: 10%
