Actually, Anthropology rather than archeology can answer some of the questions surrounding the Trojan War.
Wife stealing is not an unknown phenomenon in many cultures and is still, in this day and age, a cause for war in many primitive cultures. However, whether Helen actually existed or is merely a metaphor for something else remains to be seen --- it's quite possible that Paris did in fact steal something or give offense, but that propaganda required him to be villified in the worst possible way in order to form an alliance of Greeks. Accusing him of stealing another man's wife would most certainly have offended the civilized Greeks.
As for the Trojan Horse, anthropology might explain that too. The Greeks were the inventors of face-to-face annihilation battle. Honor and the "rules of war" as they existed at the time required a battle to be won by sheer musce power and numbers, not by trickery. Anyone who would have used brains instead of brawn on the battlefield would have been suspect. Somehow, Odysseus managed to trick the Trojans into defeat, but his explots might have disgraced him back at home.
Which might explain why Odysseus wandered for so long; he won the war, but in a dishonorable way, which caused the other Greeks to exile him.
Anyway, just an idea or two...
Odysseus' long delay in getting home was because he had offended Poseidon. Of course, there are people today who doubt Poseidon's existence.
"Honor and the "rules of war" as they existed at the time required a battle to be won by sheer musce power and numbers, not by trickery. Anyone who would have used brains instead of brawn on the battlefield would have been suspect."
This is certainly an overstatement. At marathon, the Greeks used trickery to make the Persians archers miss them with their first volley. They started out marching steadily, and then at the exact point when they knew the Persians would release their arrows, they started to run.
Almost all strategy and tactics are based insignificant part on trickery. The Greeks certainly believed in strategy and tactics. For example, they had a strongtendency to attack another city whenever it was facing internal weakness and discord.
