Mexico and Canada on opposite sides.
The feelings of the indigenous people tend to vary a lot about this topic.
Some of the indigenous people are very hostile to any foreigners in their land, so they would not hesitate to attack, and even in some cases kill.
There are some that feel it as an usurpation of their daily lives, and do not see the tourists very fondly, but are not making any real problems, just avoiding contact.
And there are some indigenous people that actually saw a nice opportunity to modernize and make a profit of the tourists, so they are using their survival skills in the wild in their advantage, and they are very welcoming towards the tourists and encourage them to come.
I do not believe that a strong nation should be able to boss around weaker nations. This is just wrong in that a nation should be free to decide what it wants to do. A strong nation can assist them in developing. How ever they should not rule them. At that point that weaker nation will be stripped by of their sovereignty. This is not that times of Empires.
