You have written so many repeating words and stating the obvious without punctuations for easy comprehension of your readers but I need to let you know that Biden is still new as the American president he ascended barely 6 months ago. As the 46th American president, he is still riding on the performance and glory of the past, there are no challenges that is new to him for the world to see his strength and policies he is going to introduce (he met covid-19, so is just a continuation for him). Biden has been printing more dollar and that may affect the currency if not probably handled.

About the black gold, nothing is permanent. Saudi Arabia is about saying they are not producers anymore and that means they are looking to diversify the economy. So oil may not be the ultimate as there are now different means to go pass the depency in the use of oil , like the electric cars that are being in use.
