Why do Russia keep using Ukrainian ports? I wonder if Russia believed that Ukraine was out of cruse missiles or they had beefed up their defenses and believed they could shoot them down?
It's a very complicated subject, but to condense it as much as possible without losing important context:
Basically Crimea was a part of the Russian SSR that the leader of the USSR gifted to the Ukrainian SSR in the 1950s (something the Crimean ASR protested about until those in charge were told to shut or or Gulag lol), it was a completely propaganda action as he was just moving it from being assigned to one part of the USSR to being assigned to another part of the USSR, both belonged to Moscow. In name it was part of Ukraine however that didn't actually become a reality until the 1990s when the Ukrainian SSR left the USSR and became a country with the same borders.
The new Russian Federation then signed treaties/memorandums/etc with Ukraine acknowledging those borders and agreeing to absorb Ukraine's share of the USSR's debt, but with some agreements thrown in, one was that Ukraine surrender it's nuclear weapons to Russia along with its Tu-22M and Tu-160 bombers, another was that Ukraine surrender it's claim to the Admiral Kuznetsov aircraft carrier which Russia had stole from Ukraine during the fall of the USSR (no joke the Kremlin ordered the Russian captain to kick off all the non Russian crew and sail it to Russia despite it not even being fully completed yet), and a final one was that Ukraine would permanently lease to Russia all the Soviet navy/army bases in Crimea (sort of similar to how Britain used to control Hong Kong). NB: That's how they were able to take over Crimea so easily in 2014, their military was already there.
And that's essentially the problem for Russia, because they had lifetime use of all the military ports in Crimea built by the USSR there was no need for them to spend money they did not have to build new alternate ports in the area, so they didn't.
The fact that another nearby ship also took enough damage to sink, would suggest other ships in the nearby port area that didn't sink may still have taken damage as well - we've seen plenty images now showing parts of the ship's hull laying in streets, on top of building and in people's yards up to 1km away from the port, so those other ships could have been hit with shrapnel as well
Indeed.
In a similar vein, it's common knowledge that the 9/11 attacks destroyed WTC 1, 2 and 7 but something those who aren't that educated on it don't realise is that they also destroyed WTC 3, 4, 5 & 6 in addition to causing major blast/fire damage to a dozen nearby buildings which took months to repair.
An explosion that size is going to cause huge collateral damage.
News says Germany has signed a historic deal; Germany will setup a base to house 5k of its soldiers in Lithuania near the border with Belarus. It's the first German foreign base since WW2
5K is almost a quarter of Lithuania's army, so this will be great for shoring up their numbers, obviously 26K won't stop a Russian invasion much better than 21K but from an international relations point of view it's good for Lithuania and European unity.
An obvious downside is that while it will be a good IR/PR relations boon for Germany it will also be a huge PR boon for Putin and Lukashenko. I can already picture Putin's rant on the Reich once more threatening their western borders
