Viewers of the Democratic National Convention were impressed Thursday night with a powerful speech by retired Marine Corps General John Allen, who joined the crowd in a chant of “USA! USA!”

The most powerful speech I've seen this election season was just given by 4 star Marine Corps General John Allen. Wow. #USA #DemsInPhilly — Kayla Poley (@kaylapoley) July 29, 2016

Retired USMC General John Allen a powerful surrogate for @HillaryClinton. I expect to see him with her weekly. — Hugh Hewitt (@hughhewitt) July 29, 2016

John Allen is a highly intelligent, highly respected Marine general. Utterly apolitical. That he's here speaks volumes. — Max Boot (@MaxBoot) July 29, 2016

If you told me 3 years ago I'd see a pissed-off John Allen on the DNC stage, I'd have demanded you immediately pass me the blunt. — Spencer Ackerman (@attackerman) July 29, 2016

It was fortunate that there wasn’t a repeat of the embarrassing “No more war” chant that threatened to drown out former CIA Director Leon Panetta the previous night. Actually, there was, but the crowd by this point in the convention had been assured that it’s OK to chant “USA!” to drown out the anti-war crowd.

Just follow your hearts, and if that fails, stick to the script.

Gen. John Allen takes the stage with veterans from Iraq and Afghanistan. As he speaks, the crowd cheers "USA! USA!" — Katie Couric (@katiecouric) July 29, 2016

Not exactly. The USA was to cover the "No More War" https://t.co/QYPfLo6ZSn — Mickey White (@BiasedGirl) July 29, 2016

@katiecouric Must be hearing something different… No more war? Your bias is showing just a bit! — Dillon Talley (@DTalley6) July 29, 2016

@katiecouric On CSpan it was "No More War" — Ma Joad (@Alek_AECM) July 29, 2016

@katiecouric They were trying to drown out the chants of "No more war!" — mantis shrimp ^0^ (@mantisbat) July 29, 2016

After a rough opening day filled with hecklers, weren’t the Democrats in the hall declared unified on Day 2?

Embarrassing visual at DNC: Gen. Allen interrupted by "No more war” chants — Zeke Miller (@ZekeJMiller) July 29, 2016

amazing to me that after that moment – "you have sacrificed nothing" – chants of "no more war" had to be drowned out by "U.S.A." — Rick Klein (@rickklein) July 29, 2016

Tonight's obligatory military pride segment met with competing chants of USA! USA! and No More War! No More War! — Michael Tracey (@mtracey) July 29, 2016

Kinda remarkable to see a hoarse 4-star shouting American exceptionalism at a Democratic crowd drowning out "no more war" chants with "USA!" — Matt Welch (@MattWelch) July 29, 2016

Shouts of “No more war!” drowned out by a flag-waving, sign-holding crowd chanting, “USA!" — Yoni Appelbaum (@YAppelbaum) July 29, 2016

The disruptions of the protestors appear to be backfiring, providing a backdrop of flag-waving patriotism to Gen. Allen’s speech. — Yoni Appelbaum (@YAppelbaum) July 29, 2016

Who expected that at the DNC? So many conflicting emotions to process.
