Turkey importance for Germany has decreased since the creation of Israel. thats why Erdogan constantly talk against Israel hoping Israel goes away and Turkey regain the position of Ottoman empire. when that Arab delegation regarding Gaza was going to China and Russia. Turkish foreign minister was missing but his now moving around in that delegation in Western Countries.Having accession talks with Ukraine means little. The EU has had accession talks with Turkey for decades with little result.
Ukraine is not Turkey. There are two conflicts going on. One is German-Russia conflict at state level and another is Putin personal conflict with Germans. it is the later conflict that has pissed German elites so much that they will squeeze the whole of Europe but continue to support Ukraine. I think Putin is well aware of it. to irritate Germans more he constantly talks about them when Arabs are present.
