Arnor- Designed For Failure?

Good point. Arnor was chosen because of it's disunion. How Sauron would have went had Arnor remained intact may have been a toss of the coin. Perhaps the indirect attacks, or the use of people inside the realms to cause disruptions may have been used anyways. He did make use of Dúnedain and clearly they are susceptible to his influence. He made a mess with them on Númenor. I think he'd have tried to slowly chip away in any case and yea Arnor did not fall so fast even though it did fall. It was around for nearly 2000 years and fighting about 600 years with Angmar.
