@slimboyfat: the pipeline was previously shut down by a fella named Trump. It’s being built by Americans since they are the only ones that have the technology to properly build in that particular location (deep sea in a geologically active area). When the Americans stopped building, Russians tried to finish it and caused a small ecological disaster (toxic grease on Baltic beaches) because their equipment is just not capable of doing it properly causing everyone in the area to tell them to stop. Not only that but the Russian produced basically a pile of junk and bolted it together, but it would have been dangerous to pump at capacity without the thing blowing up based on their shoddy work, some people were giving them 1-3 years before it would fail.
Russia and Iran talks big game, but their primary tanks (T72) are still an average 50 years old (Israel famously killed 30 Iranian tanks with just 1 of theirs in the 90s, similar the US in the Gulf War made scrap metal out of them), infrastructure building like pipeline boats is also from the last century, Iran’s navy is basically a bunch of speed boats and Russian navy has submarines that are so old, they occasionally end up on the bottom of the ocean without even being in combat. They do have numbers and willpower though so an urban combat landwar would be problematic.
The biggest question for Ukraine is whether the US would get involved, it seems like Biden doesn’t want to (I’m assuming after the Hillary hacking affair, Putin may have a bit of dirt up his sleeve) so Ukraine would have to fend for itself. If the US does get involved, not even a modernized China would want to cross that line, let alone Russia.
Germany doesn’t want to get involved because they’re dependent on Russian coal, gas and oil. Take that away and Germany basically has to shut down half the country because their wind and solar plants don’t work at night or when it’s not windy or too windy or when it’s cloudy (which is like 200 days of the year over there) and they shut down all their nuke plants as well.
