Having thwarted the attack on Dream Island launched by three nations and the ape base, and dispelled the super tsunami, Yan Fei and Dream Island remained silent, not moving to launch a devastating war against the three nations. It's not because Yan Fei didn't want revenge, but because he was waiting for his drone carrier to return to Earth.
For Dream Island now, the USA, Britain, and France are not even worth considering, and they could be obliterated effortlessly. Yan Fei's primary concern is actually the ape base, which is why he focuses his main attack on the ape base. Previous attacks have shown that the energy cannon of the super fighter jet cannot penetrate the ape base's defenses, but analysis from "Dream" suggests that the ape base's defenses have limits; while they might withstand a super fighter jet's attack, they cannot withstand the drone carrier's assault.
