"A narcissist in Washington tears world accomplishments apart; destabilizes region. US now unwelcomed everywhere in the area including Iraq; tensions escalated to feverish pitch. Taking out despicable military leader terrorist? There are a hundred like him, standing next in line," he continued.

…U.S. government leaders unconstrained by checks/balances, concocted an ill-conceived plan to divert focus from political woes. The world knows Iran is a dangerous state, but the world found a path to contain it; not perfect but by most accounts it was the right direction… — Maple Leaf Foods (@MapleLeafFoods) January 13, 2020

McCain's tweets echoed criticism of Trump's actions toward Iran, in particular the killing of top Iranian military commander Qassem Soleimani, by Democrats on Capitol Hill who have blamed the president for what they say was an unnecessary provocation of Iran without the authorization of Congress.

Trump administration officials have countered that Soleimani represented an "imminent" threat to U.S. forces or assets.
