These are examples of the infamous German Konjunktiv or conjunctive mood. They mean, in essence, should, ought to, could, would but… It ain’t gonna happen.
Take this example here: Why Germany Should Further Boost Defense Spending, and Why It Probably Won’t. Of course, the Germans know that they should, ought to, could, would spend more on defense but they just won’t because… It ain’t gonna happen. This grammatical subtlety has always worked nicely in the past, whether they were in a conjunctive mood or not. So, hey. Never touch a running system.
The United States is bristling at the suggestion Germany might miss its own defense spending target, which is already short of the NATO goal, prompting comments from officials, including U.S. Ambassador to Germany Richard Grenell.
NATO countries have pledged to move toward spending 2 percent of GDP on defense and Chancellor Angela Merkel’s government had pledged to increase spending to 1.5 percent by 2024. Last year, at the NATO summit in Brussels, Trump criticized Germany’s contribution to the NATO and Merkel countered that the European country is the organization’s “second largest providers of troops,” according to The Guardian.
“NATO members clearly pledged to move towards, not away, from 2 percent by 2024. That the German government would even be considering reducing its already unacceptable commitments to military readiness is a worrisome signal to Germany’s 28 NATO Allies.”
