Seriously, there is no evidence that the repaers could be defeated. All major battles were lost, in the galaxy map before the Battle for Earth the reapers are pushing agaisnt all systems.

The strongest argument is that the reapers would be stretched thin. But this is just a supposition based in no facts. Just look at the Battle for Earth, even though the reapers are everywhere, there are dozens of them to fight the combined fleet of the galaxy.
The reason the Reapers spread through so much territory in that time has more to do with the strength of opposing forces. The militaries of some of the larger powers were frustrating the efforts of the Reapers in a major way.
Most colonies in Human space don't have large garrisons. And most of the minor players in Citadel space have smaller militaries. Pirates, mercenary, and slaver groups are only a minimum threat to Reaper space-bourne forces.
The Asari Republics did not have a large standing military, due to their historical reliance on diplomacy and economic means to deal with other races (a major reason Thessia fell so quickly). Their military was loosely organized and focused on small unit actions. This could also be said of the Salarian Union, but with a more centralized military structure and government.
When looking at the powerhouse militaries in Mass Effect, we see a slightly different "big picture". In these cases, the Reapers were shown, for the most part, not be be infallible or invincible.
The Batarian Hegemony (the exception to this) was taken down in a classic Reaper "cut the head off of the snake" strategy. They came into Batarian Space without warning, used indoctrinated agents (Leviathan of Dis), and quickly disrupted C3 networks. Similar to what they did with the Prothean Empire, just without the Citadel. In my opinion, the Batarians would have been as much a thorn in the Reapers side as the Turians and Humans, if not for that.
Despite their blitzkrieg assault on Alliance space, a fair precentage of the Alliance Navy survived (enough to remain combat effective). The Reapers, despite having decimated the Alliance presence on Earth, and reducing the effectivness of the national militaries' operations, still did not completely subjugate Earth. This was due mostly to Shepard's warnings finally being heeded. While late in coming, it kept the Alliance from completely falling apart quickly and allowed the fight to continue (presumably coordinated/led by David Anderson Earth-side; Hackett off-world).
The Turian Hierarchy was holding fast (and like the Alliance, had some forewarning). They were taking hellacious losses, but the Reapers hadn't yet won by the time the final assault on Earth began (to my knowledge). The Krogan (potent ground forces) getting involved not only bought the Turians time, but allowed a major victory against the Reapers ( "Miracle at Palaven").
The Migrant Fleet and Geth would have been a big boost to the allies from the start, if not for their private little war. But they don't factor into my argument, unless peace is brokered between the two parties. Afterward, despite their losses in the war for Rannoch; the sheer size of their fleets, the Geth Corps, and their logistical capabilities, would have been sufficent to deny the Reapers a quick victory (even without assets of the other powers). Combined with the other allied forces, it gave the allies a chance at long term victory, even without the Crucible. A pyrrhic victory in the end. But a victory in the war, nonetheless.
This "cycle" was different from the previous one, thanks to losing the Citadel as a quick way in the back door. The Reapers had to use brute force for the most part, world by world. System by system. Cluster by cluster. Slow and steady. The good guys had time to prepare to varying degrees, thus fierce resistance. Those little Reaper icons on the galaxy map only indicate Reaper activity, not Reaper conquests. The strategic situation allowed for a fighting chance against the Reapers.
From an in-universe point of view, Hackett's opinion that the Reapers couldn't be beat conventionally was only an educated opinion as a military man. Understandable, considering the situation before Shepard organized the "grand alliance" to take the war back to the Reapers. Without that alliance, even the big kids on the block would have eventually been destroyed. With it, even if the Crucible failed (which it did, in a way), there was a fighting chance. Which was better than the situation before ME3.
Nerd moment complete. Just my opinion, by the way. Others will differ.
