Daniel Larison writes at The American Conservative,
If bringing Montenegro into the alliance is worth doing, it should be properly debated and members should vote on the record. McCain wants to avoid that debate, because there is very little for his side of the debate to say other than to engage in fear-mongering and baseless accusations.Rand Paul issued this statement:
Currently, the United States has troops in dozens of countries and is actively fighting in Iraq, Syria, Libya, and Yemen (with the occasional drone strike in Pakistan). In addition, the United States is pledged to defend 28 countries in NATO. It is unwise to expand the monetary and military obligations of the United States given the burden of our $20 trillion debt.
