The calculations for the next war just changed . I asked grok to verify the article and how this new EW prowess would affect the next round of the conflict The answer is below :
**Short summary:**
The X post is **mostly credible** — Iran did impose a nationwide internet blackout and caused significant Starlink disruptions (30–80%+ packet loss) during the January 2026 protests, likely using advanced jamming (possibly Russian/Chinese tech).
However, specific claims about exact hardware (Murmansk-BN, Krasukha-4) and it being a deliberate "test run" for Taiwan are **speculative**, not fully confirmed.
**Regarding Iran–Israel conflict:**
Iran's demonstrated ability to heavily jam Starlink suggests they could also effectively jam/spoof GPS/GNSS signals over their territory, which would degrade (but not completely block) many satellite-guided Israeli long-range munitions. Modern weapons have countermeasures (inertial backup, multi-constellation receivers), so accuracy would suffer but not disappear entirely.
