But when we are dealing with foreign occupation, it's a very different matter, and history has proven the difficulties thereof (e.g. The Vietnam War, the Soviet invasion of Afghanistan, and now Iraq and Afghanistan). In such wars, our troops are in foreign lands, knowing neither the language nor the culture of the people. This of course puts them at a great disadvantage against local insurgents who can present themselves as of the people, local liberators against a foreign occupier, and they can even point to the inability of these occupiers to even hold the simples of chats with the locals.
Based on this, would you agree that NATO should create a new military force that could recruit anyone regardless of nationality into its ranks, the minimum requirements, besides the usual capabilities that we'd expect from a national defense force, being bilingualism in the common administrative language of that force plus another language, along with a familiarity with world religions and cultures, that would be expected to go to the front lines, other national forces providing support?
