There is a nice verb in German, for which there is no translation to English.

It's called 'zerreden'.

It's the best description of such 'explanations' about Syria, like your's.

Example?

First let Assad detain and disappear 60.000-120.000 peaceful, secular activists; congratulate him for 'reforms' like letting 5,000 Islamists out of his jails, where these were extremised; then let Qatar, Kuwait and Turkey sponsor extremist gangs organized by these while doing whatever is possible to curb foreign support for secular armed groups (including taking away all of their MANPADs)...add plenty of such nonsense like 'Turkey is supporting moderate Syrian insurgents', 'CIA is doing the same too'...preferably while establishing a close alliance with Marxist/Maoist terrorist group that's completely foreign to the country in question - and then declare the entire affair for 'no matter of national interest', before, finally, concluding it just couldn't work.

Then, sigh, fighting a war for... well, gauging by Afghanistan: meanwhile it's 40+ years and there's no end in sight... is, what: 'cheaper'?

Than what?

(Disclaimer: and of course, there's no conspiracy; then any similarities to earlier, well-known and well-documented cases - are pure coincidence.)
