"There Are No Words"
Or, silent movies in comic form.
Seven scans from Avengers vol. 3, #49.
Kang has once again launched an offensive against Earth, after weakening the Avengers by putting them through battle against old enemies. In an attempt at retaliation, a group lead by Captain America and Iron Man launch a space attack against Kang's fortress and another entity called the Triple Evil, but wind up stranded in space after the fight against the latter. Kang, claiming that by attacking his fortress, the Avengers have removed the fight from "fair battlefields", decides to stop being benevolent and start eliminating civilian targets. One of his forcefield rings has enveloped Washington D.C., keeping all civilians and politicians from escaping as Kang attacks with Sentinels he commandeered from the US military. A small team of Avengers made up of Thor, Wasp, Wonder Man, and Firebird make it into the shield to take out the Sentinels, only to find out that while Kang's image is holographic enough that they can't hurt him, the reverse definitely isn't true. Wasp comes across a downed helicopter full of Secret Service and the President, and Thor uses Mjolnir to open a portal to get them out. He can't open one big enough for the entire populace, though, so their only chance is to stop Kang. Thor orders Wasp and Firebird through the portal, since he and Wonder Man can survive anything Kang might throw at them.
They still weren't expecting this.
Faced with the prospect of Kang doing this to every other major city on Earth, and having run out of defenses, the governments have no choice but to surrender.
