As the Islamic State's so-called caliphate collapses across Iraq and Syria under unrelenting pressure by the US-backed coalition, the whereabouts of the group's chieftain, Abu Bakr al-Baghdadi, remain a mystery.
Since fleeing the group's Syrian stronghold of Raqqa in May, various reports over recent weeks allege the terrorist leader either has been killed by Russian or coalition forces or is still at large in the group's redoubts in central Syria.
The impetus inside the White House and Pentagon to kill or capture al-Baghdadi has seemingly been lukewarm at best compared to the hunt for al Qaeda leader, Osama bin Laden, which ended with the Navy SEAL raid on the terrorist leader's Pakistani hideout in May 2011.

The defeat of the terrorist group also known as ISIS or ISIL, along with the death of its emir, has been the clearest objective of President Trump's national security and foreign policy strategy, and one that critics claim has been heavy on rhetoric and little else.
What remains unclear is how the Trump White House plans to carry on the fight against Islamic State once al-Baghdadi is no longer in the picture.
US military officials have reiterated that al-Baghdadi's death remains a top priority for the American-led coalition battling Islamic State. However, coalition commanders and Pentagon officials also claim that the Islamic State chieftain has been effectively sidelined from any command-and-control role over the group's operations in the Middle East and across the globe.
The Islamic State leader "is somebody who we would like to see dead," Pentagon spokesman Navy Capt. Jeff Davis told reporters July 17.

US and coalition-led operations to kill or capture Baghdadi and other Islamic State leaders are integral to the mission to dismantle and destroy the terrorist group and its affiliates worldwide, Capt. Davis said during a briefing at the Pentagon.
"Leadership strikes are important," he said of the coalition's operations to hunt down the upper echelon of Islamic State, starting with al-Baghdadi. Such missions provide the "moral authority or imperative" to American and coalition forces fighting to curb Islamic State in Iraq, Syria, and elsewhere.
But the Pentagon spokesman made clear that while the hunt for al-Baghdadi may be morally essential, his loss will mean little on the battlefield.
"Militarily speaking, he is already irrelevant," Capt. Davis said.

Those comments echo those of Defense Secretary James Mattis, who said al-Baghdadi's death would create "disarray in the enemy's ranks" and upend efforts by Islamic State to hold onto its territorial gains in the Middle East.
"We're not here to help him through his midlife crisis. We're here to give him one," the Pentagon chief said.
Top Islamic State leaders, including al-Baghdadi, reportedly began fleeing Raqqa for Deir-e-zour and Madan en masse in May ahead of the coalition's operation to liberate the Syrian city of Raqqa, which had been the group's self-styled capital in the country since taking the city three years ago.
Since his departure from Raqqa, unconfirmed reports of the Islamic State leader's demise have permeated across a number of media outlets over the last several weeks.
Russian news outlets, citing defense officials in Moscow, had reported al-Baghdadi's demise months earlier, saying he had been killed during Russian airstrikes on Islamic State positions outside Raqqa in May.

Most recently, members of the Syrian Observatory for Human Rights — which has a strong track record for accuracy in the chaotic Syrian struggle — claimed they had irrefutable evidence al-Baghdadi had been killed in counter-terrorism operations in the Deir-e-Zour area in eastern Syria.
Those claims were upended by reports from Kurdish intelligence officials who said al-Baghdadi remains alive.
"It is not about Baghdadi necessarily, there are other leaders waiting" who are former Iraqi military under Saddam Hussein, Lahur Talabani, head of the Kurdistan Regional Government's intelligence services, told Reuters July 17. "Do not expect the game to be over anytime soon for the Islamic State."
