Id have to disagree and say they are serious.... my guess!! is there are a number of new systems (technology) in the pipeline that will be some very serious hard defence against these threats.
.50cal have a variety of uses....and are always handy!!!
However in IMHO the best asymmetric!!!! http://www.strategypage.com/CuteSoft_Client/CuteEditor/Images/emsmiled.gif" align="absMiddle" border="0" alt="" /> defence against these types of threats and particularly non state actors that may conduct them is in our region " soft war" prevention of cause...
Assisting maritime governance/ restocking fishing grounds/ protecting the maritime environment/ education of the effects of rubbish and waste into the ocean etc!!!http://www.strategypage.com/CuteSoft_Client/CuteEditor/Images/emwink.gif" align="absMiddle" border="0" alt="" />
Put simply, asymmetric threats or techniques are a version of not "fighting fair," which can include the use of surprise in all its operational and strategic dimensions and the use of weapons in ways unplanned and unconventional ways. Or one who strives to exploit weaknesses or who strives to circumvent superior military power by cunning, surprise, indirect approach, or ruthlessness. Not fighting fair also includes the prospect of an opponent designing a strategy that fundamentally alters the terrain on which a conflict is fought.
