NEW YORK (TheStreet) -- German companies have purchased American companies Dresser-Rand  (DRC) , Sigma-Aldrich  (SIAL) and TRW  (TRW) in the last 72 hours, and TheStreet's Jim Cramer says this is very important because these are large deals for proprietary American companies.

Sigma-Aldrich has a 25 price-to-earnings multiple and Cramer calls it a "fantastic long-term growth story." Cramer says Merck KGaA's  (MRK - Get Report)  bid for the life sciences company was unexpected.

Siemens picked off Dresser-Rand, and Cramer notes many people thought Siemens would take a back seat to General Electric  (GE - Get Report) .

Must Watch: Jim Cramer Says the Germans Are Going to Keep Buying Our Stocks

Finally, the auto parts business "has been on fire for so long" that Cramer finds it hard to believe a company would buy TRW at these heightened levels. But it happened, and Cramer says the Germans are here and they will keep buying our stocks.
