The claim that Trump stopped 8 wars, including 5 due to tariffs, and that the threat of tariffs prevented India and Pakistan from going into a nuclear war is false because there is no independent or credible evidence supporting these assertions beyond Trump's repeated personal claims, which have been widely questioned and lack verification.
Trump stopped 8 wars, I would say 5 of them because of tariffs. The threat of tariffs stopped India and Pakistan from going into a nuclear war.

Key Evidence
Multiple reputable news outlets (The Hindu, The Economic Times, News18) document Trump's repeated claims but also highlight the lack of independent confirmation.
No official statements from India or Pakistan acknowledge U.S. Tariff threats as a factor in their conflict de-escalation.
Media reports note factual inaccuracies and confusion in Trump's narrative about the wars he claims to have stopped.
What the Evidence Shows
Multiple news sources report that President Donald Trump has repeatedly claimed to have stopped eight wars, with five of them allegedly ended due to his use of tariffs as leverage. He specifically asserts that the threat of tariffs prevented a nuclear war between India and Pakistan.
However, these claims originate solely from Trump himself without corroboration from independent officials, governments involved, or credible third-party analysts. The reported ceasefire or de-escalation between India and Pakistan in May 2025 was not officially attributed to U.S. Tariff threats by either country or international observers.
Furthermore, experts and media outlets have noted inconsistencies and factual errors in Trump's recounting, including confusion between countries and exaggerations about the number of wars stopped. No official diplomatic records or statements from India or Pakistan confirm that tariff threats directly influenced their military decisions or averted nuclear conflict. Thus, while Trump publicly repeats these claims, they remain unsubstantiated and contradicted by the absence of evidence from reliable sources.
