They are already. They just opened the first of five LNG terminals to accept U.S. LNG ships.
It is crucial that Germany has the energy required to support its industry. Germany, through the 1960 Wirtschaftwunder, has attracted a large foreign labor force(mainly Turkish) In case of an industrial standstill, these laborers will become unemployed and the country can expect social unrest on a large scale. The Turkish Gastarbeiter will not return to Turkey because of a lack of employment and lower standard of living. Germany has always been the foremost European industrial nation and therefore has the highest energy requirement in all of Europe, bar none. Germany has no choice but to slip under the Federdecke mit Amerika. Perhaps a sexless union but still a union. Amerika must supply the LNG to keep the boilers at pressure and leftover gas can be distributed to remaining EU members. An advantage of such a setup will place Germany in a position that will prevent them to repeat the two misdeeds of the 20th century. Even little Macron can breathe easier. This union will be more precious than NATO or EU and guarantees a PAX Americana while putting Ivan in a double Nelson.
