Isn't it an old staple of cybernations that "wars are won and lost in the upper tiers?"
EDIT: In regards to the Gramlins - IRON war, that was a particularly extreme case where GRE was vastly outnumbered and was undergoing massive internal problems due to the whole Ram thing.
Quickly scanning the current stats, it seems that the war currently (across all battlefields, which of course isn't exactly how it is playing out in game) is tilted heavily in DH-CnGs favor on the uppermost tiers (150k and up) a more or less even fight at this point in the next range (150-100k, though DH still has a tech advantage in this area) and lower than that swings overwhelmingly in favor of the coalition. I'd say at this point its fairly obvious the next cycle of war will determine whether the coalition can drag enough nations down from the 100K+ range to the point where they can win a convincing victory, or whether DH-CnG can preserve enough of their upper tier strength to force something resembling a draw in the overall conflict.
On the overall fronts, its beginning to look to a relatively passive observer that TOP and friends are losing the battle in their upper tier, DH may have secured an advantage on their front with the absolute slaughtering of Anarchy Inc's largest nations and on the CnG front CnG was at a disadvantage but the entry on Non Grata into this area hasn't really lasted long enough to make a conclusive deduction one way or another.
