I know this is just a funny meme, but if anyone was still wondering:
In the Silmarillion, the War of Wrath was the first time the Valar intervened in the conflict for middle earth, against the then villain Morgoth (Sauron's boss). The intervention destroyed middle earth and its many magical kingdoms, even sinking an entire continent. After this the Valar decided they should be careful with middle earth, as intervention also means a great escalation of destructive power.
In LOTR Manwë only sent the eagles after the ring is destroyed because he was staying out of the conflict until then. His intervention wasn't to help the war, but simply to return Frodo home after it was done.
