Well all I can say is we have had many years of tact and diplomacy, especially eight years just recently. Where have we gotten? We are still paying a large portion of resources spent on NATO. China still steals our intellectual property. We still pay higher tariffs on almost everything compared to what we sell. Other countries don't want to stop the Iran nuclear deal, not because it was so good, but they don't want to lose the oil. Germany wants to purchase their energy from Russia yet wants our protection from them.
Perhaps we do need to take off the kid gloves. Kindness obviously has only worked to make things worse or at the very least keep it the same.
It was once said that you need to speak softly but carry a big stick. Our big stick maybe to cut off some of the free spending.
