Turkey, like Germany, has had time to reconsider how history might think on its response to the invasion of Ukraine.
Although the country did not illuminate any iconic building in the Ukrainian flags colours, they have been providing Ukraine with cutting edge armed drones and diplomatic support against Russia for a while now.
The official Ukrainian media accounts have been praising the Turkish support since the start of the war.

No, they aren't. Spending targets aren't obligations, and there are no “arrears” from them. I know Trump popularized this line as part of his anti-NATO propaganda, but it isn't how things work.
