Former Pakistani Border Force commander and retired Lieutenant General Tariq Khan stated that Trump has pushed the United States and its Middle Eastern allies into a "dead end" in their Iran policy. The recent escalation of violence is closely related to Trump's inability to "impose his will on the outcome of negotiations." The memorandum signed between the US and Iran is stark evidence of a major US failure. This is also one reason for Trump's erratic, emotional, and erratic behavior, as the war has yet to find a political solution. Regarding the renewed conflict between the US and Iran, Khan said Trump has run out of cards to play. The US attempted airstrikes, but failed; Trump also hinted at a ground attack, but such an operation would require at least 300,000 troops. Trump may want to withdraw from the conflict, which might be the only way to achieve immediate peace, but he cannot. Khan added, "Has Trump been used by Israel? Has he been threatened, blackmailed, or coerced into doing something he now knows he cannot win? We don't know."
