Your post is the first I have heard about any limit to the duration of our funding "obligation".

Firstly, it's not an obligation. It is just smart strategic thinking.

Secondly, you must not have been reading many of my posts (which is totally cool...you can read -or not read- whatever you like). I've been setting horizons based on actual data. In 18 months, Russia is going to be experiencing a severe hardware crunch. They're going to be out of stuff, and all their boneyards will have been picked clean. I gave the estimate of 2 years to allow for a little bit of error, and also for the effects that this will have on them.

But I do agree that we should not set publicly a time horizon. That gives Russia a target to achieve. If we say "indefinite", Putin likely will know he's screwed, and seek terms that both sides can live with.
