Most educational material in farsi and even to some extent pashto books are published in Iran. Iran is investing allot of money in influencing the youth in Afghanitan. Many tajiks have converted to rafidism in the last few years.

The Americans allow this to happen as they see shi'ites as less harmful for their policies than sunni-deobandi/salafi alternative.

Iran is very effective in converting young tajiks into rafidism. This is why people are worried.
