But Paul has been trying to tamp down those concerns. In a recent Wall Street Journal op-ed, he sought to compare his foreign policy to that of President Reagan.
“I opposed the Iraq War. I thought we needed to be more prudent about the weightiest decision a country can make,” Paul wrote. “Like Reagan, I thought we should never be eager to go to war.”
Last week, Paul wrote another opinion column, this time for National Review, in which he reacted to the killing of three Israeli teenagers, allegedly by Hamas.
In the article, he referred scathingly to calls from the Obama administration for Israel to show restraint.
“How many times must Israel hear this call? Children are murdered — please show restraint. Cafes and buses are bombed — please show restraint. Towns are victimized by hundreds of rockets — please show restraint while you bury your dead once again,” Paul wrote.
The tone of the piece attracted its fair share of criticism, including from those who suggested Paul was seeking to ingratiate himself with wealthy, pro-Israel Republican donors such as casino magnate Sheldon Adelson.
Others, however, praised Paul and said his foreign policy views are maturing.
