Ukraine: Patterns of What?

Most of the news revolves around the shoot down of flight MH17.  Let's start there.

Assuming the audio above is accurate, the rebels had mltiple BUK-Ms.

The BUK which was used in the shootdown crossed the border back into Russia.

A very large number of nations are calling for a truce.  I don't think either side is going to accept it.

The OSCE has sent inspectors to the MH17 crash site.  The rebels denied them access.  The rebels claimed they found and sent the blackboxes to Moscow.  There has been at least one report the black boxes were found by the Ukrainians.  The US is sending the FBI and NTSB.

The Ukrainians claim they have taken the southeast portion of Lugansk.  They already hold the northwest portion.  

The rebels have claimed the Ukrainians are mad and attacking in a fury (related to the shoot down).

The flow of equipment into Ukraine has not stopped.  If intercepts are to be believed, the Russians are training the rebels on just the other side of the border on the equipment they are getting.  If the Ukrainians are to be believed, the Russians are coming across the border themselves in some of the equipment: supposedly around 300 troops.  No matter what, Ukraine still has a problem with the rebels.
