Commenting on the upcoming Trump-Kim summit to be held in Singapore, SMU Assistant Professor of Political Science Inwook Kim – an international relations expert and former protocol officer – noted that nothing can be guaranteed as security involves unknowables. He added that many foreign leaders will bring their own armed security personnel. They must declare to Singapore the arms and ammunition they carry and will be issued a certificate after being informed of local rules of engagement. Singapore usually assigns armed officers to shadow them throughout the trip. Another challenge of this summit is accommodating the international press contingent, which is likely to be huge, added Assistant Prof Kim.
