Can Trump unilaterally cut trade with Spain?

In a surprising move, the US president has threatened to sever trade ties with Spain, despite Spain's minimal export share to the US. This raises questions about the extent of presidential powers in trade relations. While tariffs are a common tool, the idea of cutting off trade entirely suggests deeper tensions in US-Spain relations. This situation is significant as it underscores the unpredictable nature of trade policy under the current administration and could impact global trade dynamics.
