Generals advising Trump did not want to repeat the mistakes of the past

Peter Bergen:

...
Generals Mattis, Kelly and Dunford have fought alongside each other since the 2003 invasion of Iraq. Then-Major General Mattis, then-Brigadier General Kelly and then-Colonel Dunford led the Marine force that went into Iraq in March 2003 during the initial US invasion of the country.

All of them experienced the visceral sense that US forces leaving Iraq at the end of 2011 helped pave the way for the collapse of the Iraqi army in the face of ISIS's campaign in Iraq in 2014.

None of them wanted the same scenario to play out in Afghanistan, where the Taliban is at its strongest point since 9/11 and a virulent local affiliate of ISIS has established itself.

These Marine generals also know how hard-fought were the battles in the southern Afghan province of Helmand, where 349 Marines died in a campaign that began there in 2009 and ended in 2014.

As President Trump conceded in the speech, "My original instinct was to pull out. And historically, I like following my instincts."

But Trump acknowledged that "a hasty withdrawal would create a vacuum for terrorists, including ISIS and Al Qaeda, would instantly fill just as happened before Sept. 11. And as we know, in 2011, America hastily and mistakenly withdrew from Iraq. As a result, our hard-won gains slipped back into the hands of terrorists."

Trump also showed concern about Pakistan's history of perfidy.  Indeed, there appears to be a tilt toward India on the Asia subcontinent.   In my view, the import point is that the US will not repeat the mistakes Obama made with his retreat from Iraq, and his announced withdrawals from Afghanistan.

I expect to see a renewed targeting of enemy forces.  Destruction of the enemy is the primary objective.
