Technically, it would be Queen Annis disposing of territory under her rule, and there was nothing preventing her allying with Morgana if she so chose.

As for Camelot's allies, they would have a choice, and that choice would be based on what they considered best for their own kingdoms. Uther had won their respect but Arthur was very new to the throne and, in the course of his short reign, would have taken it upon himself to execute a fellow King - not something that any other monarch is going to look kindly on him for; it could be taken as a sign that he viewed himself as superior and entitled to pass sentence on another monarch - and lost half of his kingdom.

They could be forgiven for thinking that he was not a good horse to back, and not somebody worthy of them committing their resources to. Again, it is intrusion into the succession war which makes any peace agreement a laughing stock. And Arthur could be forgiven for thinking that Annis and/or her husband were Morgana's allies all along or that his knight lost because of magic - that he was decieved.

Other kings could think that way too. Or they could think that Arthur can't control his temper like Uther(Especially, when magic is concerned). Also, they know Arthur personally(S2E10).
