a treaty with an Indian nation is not exactly the same a one with a sovereign state like the UK. for a list of reasons you probably already know the US regards the UK as a serious state worthy of respect on the world stage, unlike the Indian nations whom live at our sufferance and have no sovereignty as independent states on the world stage.

Unfortunately, you stated, "Unlike some countries the US is as good as it’s word when it comes to treaties." I don't think that any of those tribes or 'nations' would agree. The Fathers of Confederation wouldn't have agreed, either hence, Canada and the CPR, built to provide a reasonably rapid response to Americans acting on Manifest Destiny anywhere in Canada. Luckily, other than the North West Rebellion, it never had to be used as part of a military action on Canadian soil.

44*40” is approximately where the Columbia flows into the Pacific.

49* is where the border lies now. Most of the very state you live in was originally part of the colony of British Columbia, right down to Portland.

Yes, the USA is very good at keeping its word on treaties, isn’t it? At least until it wants to change them unilaterally and arbitrarily...
