You mean these satellite images? The ones that have the following quotes attached to them?
At a press conference on Thursday, August 28, Dutch Brig. Gen. Nico Tak, a senior NATO commander, revealed satellite images of what NATO says are Russian combat forces engaged in military operations in or near Ukrainian territory. NATO said this image shows Russian self-propelled artillery units set up in firing positions near Krasnodon, in eastern Ukraine.
This is an extremely misleading way to phrase things. Krasnodon is not just "in eastern Ukraine". It's right on the border. So being near it can also mean in Russia. The above comments from NATO mean nothing, assuming CNN is reporting them accurately. What about the others
Image 2 is from inside Russia and they say so. Image 3 is also in Russia. Image 5 is captioned twice, once with "Russian self propelled artillery unit inside Ukraine" and again, but this time it's again "near Krasnodon", which is practically in Russia. If there's an obviously demarcated border in this area it's hard to see based on the Google satellite images. The last image doesn't even claim to be of anything in particular, the caption is merely summarising story in general.
Both Russian and Ukranian troops appear to regularly cross the border without realising it - there have been repeated reports of Ukrainian forces entering Russia and then being redirected back across the border, with no obvious blowback. Given these things, and the fact that western media is in full-blown propaganda mode and not even hiding it, I'm going to want way stronger evidence than this.
But honestly, even if Russia did invade, this would merely make it on par with the USA and UK, both countries that practically revel in invading other countries and wading into other countries civil wars. So a part of me couldn't get too excited even if it did happen. It's definitely NOT worth a serious, major conflict between Russia and the west.
