German Chancellor-in-waiting Friedrich Merz reached an agreement with the Greens on Friday on a massive increase in state borrowing just days ahead of a parliamentary vote next week.

The debate over the deal cast defense spending as an issue of growing urgency as doubts increase about the U.S. commitment to European allies. Long-term strains on Germany’s debt limits, combined with the recent shift in U.S. security policy under President Donald Trump, pushed the negotiations into a deal that now goes before the parliament.

The agreement between centrist parties, led by the likely next chancellor, Friedrich Merz, was billed as a response to America’s shrinking security guarantees.
