The decision by President Donald Trump to withdraw from the Joint Comprehensive Plan of Action (JCOPA) nuclear pact has made both the EU and other signatory countries like China and Russia scramble to try and save the deal, but their life support packages are not certain to overcome the drastic US financial and trade curbs on complying companies.
The current OPEC plus agreement seems to be holding but the withdrawal of the US from the Iran nuclear deal has created some uncertainties going forward, with new red lines and slogans from all parties. Sometimes slogans can lead to far reaching consequences.
Just like Russia seems to be holding the key as an arbitrator between warring parties like Iran and Israel in Syria , China is playing an important background role to get North Korea reach a successful outcome with the USA .
They tried their best but with an unpredictable US President, nothing is certain. In turn, President Macron of France and German Chancellor Angela Merkel came to and went from Washington but the assessment of many is that President Trump was not moved either by an over extravagant show of affection from the French President or a more cooler and focused argument approach from Chancellor Merkel.
For decades the US greenback dollar has dominated the international financial and trading system with few challengers, and not even the Euro has been able to assume as important a role as the US dollar.
