仕向ける ('to induce, lead someone to, manipulate into') is a slightly negatively-coloured verb for engineering a behavior in someone — sets up a context where they'll respond as desired. Combined with ~ように ('so that'), the structure becomes 'set up so that [Y will happen].' に対し is a slightly stiffer/written variant of に対して ('toward'). のだろう combines explanatory の + conjectural だろう — 'it's probably the case that.'
