The difference, IMO, is you have a bunch of Arab nations (Enemies) around you that will not let it happen unless ya'll conquer them all, we did not. Texas alone conquered it's land and defeated Mexico which created the Southern border here.
Don't know much about Canada but they are no threat. They were conquered too, they have many Indian reserves.
The Muslim population is way, way too large to conquer, to change their stance of infidels and jihad. They hate us and always will...
For those who understand this, it is basically two brothers fighting. Isaac (Israelites) and Ishmael (Arabs):
GENESIS16:
10 Then the angel added, “I will greatly multiply your offspring so that they will be
too numerous to count.”
11 The angel of the LORD proceeded:
“Behold, you have conceived and will bear a son.
And you shall name him Ishmael,
for the LORD has heard your cry of affliction.
12 He will be a wild donkey of a man,
and his hand will be against everyone,
and everyone’s hand against him;
he will live in hostility
toward all his brothers.”
