Re: that foreign elements were behind it
The current dismal state of their economy is the direct result of the US unilaterally leaving the agreement and bullying all companies that use dollars into stopping their (legal) investments there. The other signatories are either unwilling or unable to help, which doesn't make them look like trustful partners.
That can only push their government to become even more authoritarian to keep order, with a good enough claim of the moral high ground that it can last for a good while still.
Things will probably get worse :/
