The ultimate political tool is war, whether overt or covert. It is the worst means and that is why aggressive wars are defined as war crimes. The best means of politics is diplomacy, i.e. personal exchange, in order to settle conflicts, to clear them up and to define common interests.
Deliberate escalation requires speechlessness, i.e. disorientation. The US conflict in Iran is an expression of a US escalation that lacks any art of diplomacy and negates the internationally enshrined requirement of sovereignty of the nations.
The United States’ refusal of entry to Iran’s foreign minister is a breach of the UN agreement with the United States as the host country of the United Nations. Under this agreement (1947), the United States is required to give foreign diplomats access to the United Nations at the United Nations headquarters to grant in New York.
The US position on this issue has nothing to do with the art of diplomacy, but is an expression of conscious escalation with the aim of marginalizing this multilateral event, which was founded on the experience of the two world wars. What does this mean for the international community ex USA? Doesn’t this lead to the need for solidarity ex USA (USA only 4.3% of the world population, approx. 15% of world GDP)?
However, the question remains; what’s next? How will the US deal with unwanted competitors or partners in the future? Will Washington throw any diplomatic standards overboard towards the EU, Russia or China at some point or even in the near future? If the USA no longer understood itself as an embedded member of the international community, such behavior would be understandable. Hard to imagine, because then the USA would have to think about its global roles and tasks and reposition itself. The key to a peaceful world is simple, it’s predictability. This formula applies to all countries in the world, but especially to the leading nation of the democratic and free West.
