Since Washington doesn't do diplomacy anymore, we only have two tools left: a) sanctions, and b) military force.
It appears that sanctions will soon be a tool of the past, which means that our violent foreign policy will become even more violent.
Take for example, Nord Stream 2.

Germany has been assured by the United States that any sanctions imposed on Russia will not affect the building of pipelines from Russia, a spokeswoman for Germany’s economy ministry said.

Nord Stream 2 will have a crippling economic effect on Ukraine, which will suddenly have no leverage in Europe's energy market.

Nord Stream II would run alongside the original Nord Stream pipeline and deliver an additional 55 billion cubic meters of gas, effectively doubling the project's capacity. The completion of this pipeline, and the launch of Turkstream, would strengthen the Kremlin’s stranglehold over Europe’s energy security and jeopardize the economic and physical security of Central and Eastern Europe – Ukraine most of all. Despite protests from the United States and a number of European countries, the political and economic momentum behind Nord Stream II may be too great to overcome.

Turkstream is another way that Russia is gaining independence despite our sanctions. Turkey, our NATO ally, is openly defying our sanctions as well.

The U.S. will take the unprecedented step of imposing sanctions on a NATO ally when Turkey receives a Russian missile defense system, according to a State Department official testifying before Congress.

The delivery of the S-400s will impair military cooperation between the U.S. and Turkey and will damage relations between the countries more generally, Wess Mitchell, U.S. Assistant Secretary of State for European and Eurasian Affairs, said Tuesday in testimony to the Senate.

Turkey is defying us in two different ways.

Turkey has said that it does not plan to honor a U.S. call for countries to stop importing oil from Iran, calling the demand "not binding" on Ankara.

"We will follow if there are decisions, sanctions by the United Nations on this issue. Other than this, we will only follow our own interests," Turkish Economy Minister Nihat Zeybekci said.

Washington on June 26 warned its allies that they must end Iranian oil imports by November 4 or they will face penalties under sanctions the United States is reimposing on Tehran.

I don't see how an alliance can survive if one side is imposing sanction on top of sanction.
