India is much more likely to foot a large portion of the bill than Canada given their relations with their land border neighbors.
labor is cheaper
cons:
regardless of whether we build only a land wall or both a land and water wall, this is less efficient. Especially when you want to build on the Himalayas.
building a wall, and thus, cementing highly disputed borders in the region could result in war between high population countries with nukes.
Nah, white clearly has advantage here.
