Total rubbish
All of the USA's military actions were either to protect the source of the raw materials it needs ( oil for example ) or because of the fear that the megga wealthy might have their "rights" to profit vastly from the under paid labour of others be challenged , thus the massive amount of money that went into anti communism / socialism properganda and wars .
The only case where one could say "freedom" was preserved by US actions is Korea and even then some would consider that Korea happened because of fear that US investments in rebuilding Japan would be under threat from the Chinese communist who were being supported by the Russian communist in repayment for the massive support with both men & materials the Russians got from the Chinese during WWII ( bet you were unaware of that )
I might note that despite the white governments best attempts to wipe them out, the Indigenous peoples of Australia have had freedom for over 80,000 years.
The communist people in Vietnam have quite a lot of freedom almost on par with most Western countries, the only read difference being that the Party Officials are profiting from the economy rather than the elite class ( Rockerfellas / Fords etc ) in Western economies .
Eventually totalitarian government will fail, look at what is happening in Brazil & Burma right now.
However what keeps totalitarian governments in power is support from external sources with a vested interest in benefiting from the regeime
The Talibahn are largely using Chinese weapons because China realized that they could become an ally of Afghanistan , thus not need to spend a fortune on border protection.
They can then access the vast amounts or rare earth resources to feed their manufacturing industry that is undermining the viability of manufacturing in the USA ( & the rest of the west ) plus allow the Afgans to ramp up opium production which will also find it's way into Western economies doing massive economic & social damage .
For China a win win win situation. The real loosers are Afgahn women but then again remember the West used to burn witches 150 year ago, women could not vote 75 years ago , most religions banned women from being church leaders and some still do so "freedom" is a some what relative concept .
The USA was in Afghanistan for the same reasons , to contain China by surrounding it with Western style democratic governments and of course to access the same rare earth minerals.
Russia was there for the same reason , border protection & minerals & the UK before them again for the minerals .
