You do not need a warrant for international communications performed by non-citizens (whether inside or outside the country) You do need a warrant for communications done by citizens domestically. PRISM did not change that, it has been the same for centuries. So even if PRISM captures domestic communication, a warrant is still needed to view it. There has never been a time in US history when then feds didn't have access to warrants to tap communications.
