America is making the world less safe by threatening their allies. Russia and China will see an opportunity to expand the land grab in Europe and Southeast Asia. This might be a new axis of power reminiscent to WWII, except that America is now on the other side. The similarity is in denigrating and deporting migrants, talks of annexing Gaza, Panama, Canada, and Greenland, and his withdrawal from the world stage. Don't forget he started retaliating against his political rivals (Russia anyone).
